Avoiding taxes on out of state delivery is one thing, but transport of TC is not easy to manage.
Mentioned uship is just net broker with no insurance and no liability.
It is your obligation to check who will bid on your transport and select reputable carriers from hillbillies who drive 1981 F250.
Chances are that when F250 breaks - you will have to collect the camper from the side of the road in the middle of nowhere.
Living in CA I have big incentive of buying vehicles and RV far away and doing it more than 10 times, always squeezed small vacations out of it.
