When we bought the RV, we owned a car that could be dolly towed, so we bought a dolly at the same time. Drove the car to pick up the RV and had them show us how to strap the car onto the dolly.
Fast forward 3 years - the car is worn out and must be replaced. We bought a manual transmission Subaru that can be towed 4 down. We sold the tow dolly on Craig's List and put that money into the base plate/tow bar needed for the Subaru.
We are happy campers. (While i definitely prefer towing 4 down, if we had to go back to a dolly for some reason, I wouldn't complain.)
