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.
