I use a Master Tow dolly that I bought used 6 years ago. Driving up onto the dolly should be done carefully with another person to help direct. Once you have done it several times, it can be done alone, but again very slowly up the ramps. Hopefully the dolly has brakes which are needed to save wear on the motorhome brakes. It does take more time to get the car up and secure on the dolly than a tow bar, but you will get used to doing it. the only problem that I have had was when I bought a new car and the front of the car hit the ramps because car is so low in the front. Solution was to add wood onto the ramps enough to raise the car up. Check the straps when you stop at a rest area as the straps tend to stretch and you need to ratchet up a little. Good luck !
