How much does it cost to flat-tow a vehicle behind a motorhome?

To flat tow behind a motorhome, you can figure the cost runs about $4-6,000 once you get all of the things.

You’ll need:

1. A tow bar to connect the car to the rear of the RV
2. A baseplate on the car to connect to the tow bar
3. A braking system for the car
4. An emergency breakaway switch/control for the car
5. Wiring kit for the car so that the turn signal and brake lights work
6. Likely an adapter/cord from the 7-pin connector on the RV to a 6-pin connector

Plus installation costs.
