Tow Bars

Flat towing remains the preferred dinghy method for serious RVers because it lets you pull a daily-driver SUV or truck behind your coach without loading onto a trailer or tow dolly. Our flat tow bar lineup covers the most-towed vehicles in Canada — Jeep Wrangler JL, Ford Bronco, Chevy Equinox, GMC Sierra 1500, Chevrolet Silverado 1500, Ram 1500, Toyota Tacoma, and select Ford F-150 configurations. Whether you're setting up a fresh flat tow rig or replacing aging components, every part on this page is sized to your tow vehicle's weight class and your motorhome's hitch receiver.

What's Included in a Complete Flat Tow Setup

A proper flat tow setup is more than just the tow bar — every component has to match your tow vehicle, your motorhome, and Canadian provincial towing regulations:

• Flat tow bar — Blue Ox or Roadmaster, sized to your tow vehicle's weight rating
• Flat tow baseplate — vehicle-specific bracket that mounts to your tow vehicle's frame and accepts the tow bar arms
• Supplemental brake system — required in most Canadian provinces for towed vehicles over 1,400 kg, with portable RViBrake units and permanent installs available
• Flat tow wiring harness — connects tow vehicle lighting to the motorhome's 7-pin connector for legal road use
• Safety cables and breakaway switch — mandatory for highway towing and provincial inspections
• Hitch components and tow accessories — see Hitches and Hitch Accessories for receivers, ball mounts, and pin locks

Frequently Asked Questions

What vehicles can be flat towed behind a motorhome?

Only vehicles approved by the manufacturer for flat towing should be towed four-down behind a motorhome. The most popular flat-towable vehicles in Canada include the Jeep Wrangler JL, Jeep Gladiator, Ford Bronco, Chevy Equinox, Ford F-150 (select 4WD configurations), Ram 1500 (select configurations), and certain GMC and Chevy trucks with manual transfer cases. Always confirm flat-tow approval in your owner's manual before purchasing a baseplate or tow bar — towing a non-approved vehicle can damage the transmission and void your warranty.

What is the difference between flat towing and using a tow dolly?

Flat towing — also called four-down towing or dinghy towing — pulls a vehicle with all four wheels on the ground using a tow bar attached to a baseplate on the towed vehicle. A tow dolly lifts the front two wheels off the ground and rolls the rear wheels on its own axles. Flat towing is faster to hook up, takes less storage space, and doesn't require a place to park the dolly at your destination. Tow dollies allow you to tow vehicles that aren't flat-tow approved, but require more setup time and storage.

Do you need a supplemental brake system when flat towing in Canada?

Most Canadian provinces require a supplemental brake system on any towed vehicle over 1,400 kg (about 3,000 lbs), and provincial regulations vary. Even when not legally required, a supplemental brake system dramatically reduces stopping distance, protects your motorhome's brakes, and is required by most RV insurance policies for flat tow coverage. Portable systems like the RViBrake transfer between vehicles, while permanent systems install once and stay in place.

What is a baseplate and why do you need one for flat towing?

A baseplate is a vehicle-specific steel bracket that bolts to the frame of your towed vehicle and provides the attachment points for the tow bar arms. Each baseplate is engineered for a specific make, model, and year — a Jeep Wrangler JL baseplate will not fit a Ford Bronco, and a 2018 Wrangler baseplate may not fit a 2024. Baseplates from Blue Ox and Roadmaster install behind the front bumper for a clean look when not towing.

Is Blue Ox or Roadmaster a better tow bar brand?

Both Blue Ox and Roadmaster are top-tier flat tow bar brands trusted by full-time RVers. Blue Ox is known for non-binding disconnects, lighter aluminum tow bars like the Avail and Aventa LX, and excellent customer support. Roadmaster builds rugged steel tow bars with a reputation for durability and offers strong all-terrain models. The better choice depends on your tow vehicle weight, motorhome hitch type, and whether you prefer aluminum or steel construction.

What equipment do you need to flat tow a vehicle behind an RV?

A complete flat tow setup requires six core components: a flat tow bar rated for your vehicle's weight, a vehicle-specific baseplate, a supplemental brake system, a flat tow wiring harness for tail lights and turn signals, safety cables, and a breakaway switch. Many setups also use a charge wire to keep the towed vehicle's battery topped up during travel. Browse our complete Towing Components collection for harnesses, cables, and connectors.
