Max Cargo Capacity	500 lbs
Hitch Receiver Size	2-inch compatible
Carrier Dimensions	72″ L x 36″ W x 6″ H
Construction	Weatherproof steel with 10-year limited warranty

What We Found

Mockins XXL is built for RV owners who want more carrying space without turning the back of the vehicle into a full trailer. The rack uses a heavy-duty steel frame with a stated 500 lbs capacity and a large 72″ x 36″ x 6″ platform.

It includes a raised shank, hitch lock, and hitch stabilizer that are meant to improve ground clearance and limit movement. For visibility, it comes with rear lights and reflectors, plus the license plate bracket for compliance when you’re fully loaded.

The setup relies on three heavy-duty ratchet straps with spring-loaded latches – so the cargo needs to be strapped down correctly to stay stable. After you unload, the folding design lets you store the basket upright instead of leaving it hanging back there permanently.

Who It’s For

This carrier makes sense if you’re primarily hauling bulky cargo – camping gear, coolers, lawn chairs, or other items that don’t need to be flat-towed as a vehicle. It’s also a fit for RVs that already have the compatible 2-inch receiver hitch.

Because it folds and is aimed at storage efficiency, it’s a good match for shorter weekend trips where you want the rack ready when you need it and out of the way afterward. Just keep expectations aligned: this is for carrying cargo, not for a true flat-tow setup.

The lights and plate bracket are helpful if you’re making frequent road stops and want a more complete visibility setup.

Tow Rating	7,500 lbs
Tow Bar Weight	under 40 lbs
Receiver Compatibility	2-inch x 2-inch receiver
Finish/Protection	black powder coat with fully sealed design

What We Found

CURT 70001 Rambler is aimed at a straightforward flat-tow experience. It uses non-binding latches intended to make disconnecting easier even when roads get uneven. Auto-locking arms are designed to help speed up hookup since you’re not spending as much time aligning parts at the hitch.

The bar is rated at 7,500 lbs and uses solid steel construction, plus a black powder coat and sealed design for corrosion resistance. It also includes protective rubber sleeves and safety cables, and the tow bar weight stays under 40 lbs, which matters for handling and storage.

The receiver fit is built around a standard 2-inch x 2-inch hitch receiver, and it’s meant to work with CURT or Blue Ox baseplates sold separately.

Who It’s For

I’d point this toward RV owners who are flat towing a dinghy-style vehicle and want latch behavior that’s less finicky on rough roads. The under-40-lb weight is especially helpful if you set up regularly or store the bar in a tight compartment.

It’s also a good choice if your RV uses a standard 2-inch receiver and you’re pairing it with compatible CURT or Blue Ox baseplates. If you’re relying on the included safety cables, that extra layer is a plus for people who tow often and want confidence beyond the primary connection.

Tow Rating	8,500 lbs
Kit Contents	tow bar, Jeep baseplate, safety cables, cover, 4-way wiring, hitch logo
Compatibility	2018-2026 Jeep Wrangler JL with standard bumper
Design	hidden baseplate with foldaway tow bar

What We Found

Blue Ox Alpha BX7390 is designed around a specific match: a 2018-2026 Jeep Wrangler JL with the standard bumper. Instead of treating compatibility as a guess, this kit includes a Jeep-compatible baseplate (hidden design with reinforcements) and the tow bar itself, so you’re not left wondering how everything should interface.

The tow bar is Class III steel and rated for up to 8,500 lbs, with quick-disconnect hookup pins and easy-release locking handles. It also uses a foldaway storage design to keep things cleaner when you’re not towing.

For the lighting side, the kit includes wiring (supporting brake and turn signal integration), a storage cover, and safety cables. There’s also a 3-inch rigid hitch logo included as part of the kit’s overall system.

Who It’s For

This is for Jeep Wrangler JL owners who want vehicle-specific parts rather than universal hardware that depends on measurements and interpretation. If you tow frequently, the labeled, vehicle-matched kit approach can make setup feel more consistent trip to trip.

The hidden baseplate design is also a big selling point if you care about appearance when the Jeep isn’t being flat-towed. Capacity-wise, it’s built for heavier dinghies within its rated class – assuming you follow the Jeep baseplate/towing guidelines and keep the whole setup within spec.

Connector Type	7-pin to 6-pin
Max Extension	10 feet
Cable Style	coiled flexible cable
Warranty	1-year

What We Found

CXTM’s 7-pin to 6-pin adapter cable solves a common flat-tow wiring mismatch: your RV uses a 7-pin system, but the towed vehicle uses a 6-pin setup. The coiled design extends up to 10 feet, which can help you route wiring around moving suspension parts and avoid tugging during turns.

Since it’s coiled, it’s less likely to drag and snag compared to a straight cable. The cable uses thermoplastic rubber protection designed to resist oil and wear, with a claim of high electrical and thermal conductivity plus insulation that’s resistant to oil, chemicals, and abrasion.

It’s also plug-and-play, arriving pre-made so you don’t have to rewire anything. The easy-grip connectors are meant to make coupling and decoupling simpler at each stop, and a 1-year warranty is included for non-human-caused issues.

Who It’s For

This adapter is for RV owners towing with a towed vehicle that has a 6-wire trailer connection while the RV side is set up for 7-pin. It’s especially useful when you’re stopping and starting often, because repeated plugging/unplugging is exactly where connector wear becomes an issue.

The 10-foot coil reach helps if the towed vehicle sits farther back or if your route needs extra slack.

If you’re trying to fix wiring compatibility without changing your RV lighting setup, this is one of the more direct ways to do it – just make sure the pinout and vehicle lighting requirements line up correctly.

Compatibility	Rhino Tote Tank Kits 39000, 39002, 39004, 39006
Tow Loop Size	3-inch tow loop
Ball Compatibility	up to 2 5/16-inch hitch ball
Construction	black powder-coated steel

What We Found

Camco Rhino Tote Tank Tow Adapter 39016 is specifically for moving a Rhino tote tank with less manual carrying. The tow adapter is removable and made of steel with a powder-coated finish to resist corrosion and road grime.

It lets you either roll the tote like a suitcase or tow it slowly behind a golf cart or truck. A 3-inch tow loop accepts up to a 2 5/16-inch hitch ball, making it a straightforward match to common towing hardware.

The adapter is meant to act as the interface between the Rhino tote tank kits and simpler towing/rolling methods. It also comes with stated dimensions (19 5/16 x 5 5/8 x 3 1/8 inches) and weighs about 2.6 pounds, which helps keep it from becoming a storage burden.

Because it targets Rhino tote tank kits by part number, fit depends on matching your existing tote kit model.

Who It’s For

I’d recommend this for RV owners who already have a Rhino tote tank system and want an easier way to transport it to dump locations – especially at campgrounds where the path is longer, uneven, or just inconvenient to carry over.

If your tote includes wheels and you still end up doing a lot of lifting, rolling or slow towing can reduce strain on your hands. It’s best for people who are already invested in the Rhino Tote Tank Kits (by the referenced models), since compatibility is tied to that ecosystem.

It also suits seasonal travelers who want an accessory that packs and stores without taking up much space.

Compatibility	CURT tow bar #19745
Safety Pin Compatibility	#19746
Construction	steel with black powder coat
Included Hardware	2 brackets, bolts, nuts, washers

What We Found

Wyckoff Adjustable Tow Bar Bumper Brackets are a mounting-focused accessory meant to support RV dinghy towing using a compatible tow bar. These brackets are built to match CURT tow bar #19745, creating a secure interface at the bumper.

They bolt to the bumper and integrate with safety pins #19746 for added towing safety. The brackets use strong steel with a black powder coat finish to help resist corrosion. In the box, you get two brackets plus bolts and nuts/washers, which supports straightforward installation.

This isn’t a product that changes tow capacity or towing geometry – it’s mainly about tightening up the bumper-mounting connection where looseness or misalignment can affect how the dinghy tow setup feels.

Who It’s For

This is for RV owners who already own CURT tow bar #19745 and need bumper brackets that match the system. It’s a good fit if you’d rather use a direct bolt-on solution than improvise mounting methods.

It can also work for drivers towing smaller vehicles behind an RV who want a safer, compatible connection using the matched safety pin approach. Installation will go smoother if the bumper is in good condition and you take the time to align things carefully during setup.

I’d shortlist it most when you need replacement brackets or a second arrangement for a multi-vehicle towing setup.

Tow Rating	5,000 lbs
Coupler Type	2-inch ball coupler
Max Opening Width	42.5 inches
Construction/Protection	high-tensile structural carbon steel with rust-resistant powder finish

What We Found

The 5000 lbs universal bumper-mounted folding towing bar is positioned as a basic flat-tow interface, built from high-tensile structural carbon steel. It claims a 5,000 lbs towing capacity and uses a weatherproof powder finish intended to resist rust, bending, and fatigue.

It includes safety chains and high-hardness structural bolts, which creates a multi-layer connection designed to help prevent accidental uncoupling. The kit uses a 2-inch ball coupler and features an integrated adjustable opening width up to 42.5 inches, plus a folding design that collapses for storage in smaller RV bays.

It’s also described as multipurpose – intended for towing cars, small trucks, and utility trailers – so it’s not strictly limited to RV dinghy towing. As with most universal-style bars, the biggest variable is fit: universal claims still depend on bumper and receiver geometry matching your setup.

Who It’s For

This tow bar fits RV owners who want a universal bumper-mounted option that folds for easier storage. It’s most appropriate when your towing setup already works with a 2-inch ball coupler and the bumper structure in your RV is compatible.

The adjustable width can help across different bumper/frame configurations as long as you measure carefully and confirm you’re within what the bar supports. If you tow less often but want dependable basic safety hardware like safety chains, this can be a practical choice.

It also suits people who want one hardware solution for moving equipment or trailers around a destination – not just flat-towing a single vehicle.

What to Look For Before Buying

The best car to tow behind an RV isn’t just about the tow bar – it’s about making sure the entire connection system matches. Start by confirming the tow bar rating and the way it mounts (baseplate/bumper and receiver size). Then check lighting needs so you have the right wiring adapters and a proper 4-way signal setup. Finally, I’d prioritize corrosion resistance and safety features like locks and safety cables, because those details show up every time you hook up.

Check Match capacity and hitch interface

Make sure the tow bar (or coupler) rating exceeds the weight of the vehicle you’re towing. Then verify the hitch interface – receiver size and the shank dimensions – match your RV. If you’re looking at universal options, measure bumper clearance and the opening width the bar needs. For vehicle-specific kits, confirm the exact year range and bumper style before ordering, and lean on the manufacturer’s towing guidance to avoid mismatches.

Value Choose the right kit scope

Pay attention to how complete the kit is. Some listings include the tow bar plus wiring, baseplates, and covers; others are just the tow hardware. A fuller bundle can save you from missing-part headaches. For wiring, confirm whether you truly need a 7-pin to 6-pin adapter (and whether it matches your towed vehicle’s connector). For cargo carriers, double-check that the listing includes the lights and plate bracket you’ll need for road visibility.

Rating Use rating and warranty signals

When ratings and review counts are available, I’d use that as a quick sanity check – but I also look for supporting signals in the listing. If star ratings aren’t there, warranty length and the presence of safety components (like safety cables) matter more. Powder coating and sealed construction are good signs for corrosion resistance. Weak documentation should be treated as a prompt to verify fit and installation guidance before purchase.

Verify Verify wiring and legal visibility

Flat towing only works when the lighting is right. Confirm the connector type and wiring/pin compatibility between the RV and the towed vehicle, and make sure your setup includes the 4-way brake/turn signaling integration your system needs. If you’re towing on public roads, verify you have the required visibility components (like reflectors or tail lights, as applicable). For cargo carriers, check that the license plate mounting solution fits local requirements. After installation, test every light before departure.

Frequently Asked Questions

Do towing cargo carriers count as towing a car behind an RV?

No. Cargo carriers are for moving gear behind an RV, not for flat-towing a vehicle. Flat towing needs the right tow bar plus the correct mounting hardware (baseplate or bumper brackets) and proper wiring for brake/turn signals. If you’re towing a car, confirm the vehicle is rated for flat towing and that your tow setup supports it.

What tow bar features improve safety on rough roads?

Non-binding latch designs help prevent disconnect issues on uneven terrain. Safety cables add redundancy if the main connection fails. I’d also look for sturdy steel construction and corrosion-resistant finishes, since tow bar hardware sees repeated outdoor exposure. Quick-disconnect pins can make hookup and alignment easier, which reduces the chance of a rushed setup.

Are wiring adapters enough for flat towing?

Wiring adapters help you match connector types, but they don’t automatically guarantee your signals will work correctly. The towed vehicle still has to accept the signals your RV sends. Confirm whether you need a 4-way setup for brake and turn lights, verify pin mapping compatibility, and test every light after installation.

Do universal tow bars work for every vehicle?

Not always. Universal tow bars can work, but fit depends on bumper strength, measurements, and receiver/coupler geometry. If you go universal, measure carefully before buying. Vehicle-specific kits reduce uncertainty because the mounting and components are designed for a particular vehicle configuration. If compatibility is unclear, I’d choose a kit intended for your specific model.

What maintenance prevents tow bar and adapter corrosion?

Powder-coated steel and sealed designs help reduce corrosion risk, but it’s still smart to rinse off road grime after salt exposure and dry the hardware. Regularly inspect pins, latches, and safety cables for wear. Replace damaged straps, cables, or wiring connectors rather than trying to “make it work.”

🎯 Final Verdict

If I’m choosing one option for a car flat-tow behind an RV, I’d start with the CURT 70001 Rambler Steel RV Tow Bar for its non-binding latch design, lighter handling, and included safety cables. For a more vehicle-specific, more complete kit experience, the Blue Ox Alpha BX7390 is the stronger alternative when you have the compatible 2018-2026 Jeep Wrangler JL setup – especially because it includes hidden baseplate integration and wiring. In both cases, match the capacity, confirm the baseplate/receiver compatibility, and test lights before every trip.
