Flat towing a vehicle behind your motorhome requires the right equipment across every part of the connection, from the tow bar itself to the supplemental braking system required by most states. Getting the setup right matters for both safety and legal compliance on the road.

Our selection covers tow bars from Blue Ox, Roadmaster, and Demco in capacities ranging from 6,000 to 15,000 lbs, along with supplemental braking systems from Blue Ox, SMI, and Demco for both standard and Freightliner or Spartan chassis applications. We also carry electrical wiring kits, LED tail light kits, safety cables, hitch locks, drop receivers, tow bar covers, and Demco Kar Kaddy trailer dolly winch assemblies.

Before ordering, confirm the receiver class of your motorhome, the gross weight of your towed vehicle, and the supplemental braking requirements of the state you are in.

What do I need to flat tow a vehicle behind my motorhome?

A complete flat tow setup has five parts: the tow bar, a base plate bolted to the towed vehicle's frame, safety cables, a wiring kit so the towed vehicle's brake and turn lights follow the motorhome, and a supplemental braking system. The base plate is specific to the towed vehicle's year, make, and model and is usually sold separately from the RV tow bar, so confirm it is compatible with your tow bar brand before ordering. Also check the towed vehicle's owner's manual to confirm it can be flat towed with all four wheels down. Plan to hook up and unhook on flat ground. At uneven sites, Lynx RV leveling blocks level the motorhome after you disconnect.

How do I choose the right RV tow bar capacity?

The tow bar's rated capacity must be equal to or greater than the loaded weight of the vehicle you are towing. Next, check your motorhome's hitch receiver rating and its maximum towing capacity. The lowest of the three ratings is your actual limit. Most motorhome tow bars connect to a 2" receiver. The tow bar should sit close to level between the motorhome and the towed vehicle, generally within about 3". If the receiver and base plate heights differ by more than that, you will need a drop or rise adapter.

Do I need a supplemental braking system with my motorhome tow bar?

In most cases, yes. A tow bar connects the vehicles but does not brake the towed vehicle. Most states require supplemental braking once the towed vehicle exceeds a set weight. Those thresholds vary by state and province, so check the rules for every state on your route. A supplemental braking system is a different product from the drum brakes on a towable RV. If you are servicing the axles on a travel trailer or fifth wheel, see our RV brake assemblies.

Should I buy a used RV tow bar?

A used tow bar can work, but inspect it before you buy. Check the following:ul>li>Arms extend and lock without binding/li>li>Latches and pins are not worn/li>li>Safety cables are not frayed and have intact hooks/li>li>The capacity label is still readable/li>li>It is compatible with your base plate brand/li>/ul>A missing pin or a mismatched base plate connection can stop a hookup entirely. The tow bars in this collection are new, with known capacity ratings. Text or call 817-984-1852 with your motorhome and towed vehicle details, and our team will help you confirm the right fit before you order.
