We dollied back when we first got started. Toyota Camry. didn't like the idea of getting into the wiring and risk screwing up a computer. Bought a set of magnetic lights with long wire. taped the bottom of the lights to save scratching and was ready to go. The lights on the dolly were lower than I liked and certainly didn't want a collision from the rear. Wanted something high enough to be seen.
Only problem was the dolly when we got parked some place like Ocean Lakes where the sites are very tight. solution was sliding the tongue of the dolly under the MH with the tires and axel close to the back of the RV
