I tried one time without a toad and tried Enterprise. They said they had a car if I could get there. I bummed a ride there and got dropped off. When I got in there was no car and I ended up taking a taxi home. That was my first and last time with Enterprise. I will take a toad with the GMC when it is ready for use and don't need one with the Roadtrek since it fits into a normal car space. If I had to go with a dolly I would give up RVing. I did that for 10 years and then went 4 down for the last 12. The dolly is only for very young people who enjoy getting down on the dirt in the rain to fasten the straps on the tires.
