Hi Andy. You can rent a
Trillium from the factory in Brea, California....it's in Orange County in Southern California. The problem might be renting a vehicle to tow it with....maybe
UHaul would rent you a truck with a hitch. I doubt you will find a car.
Seems most tourist from Europe go the motorhome route. Just much easier. Plus, I think they will rent you all the other stuff to go along, kitchen stuff, camp chairs, etc. Good Luck.
