Thanks for all the good info. We have thought of buying 5er in Az, but I already have a 30 ft 5er at home in B.C. I don't really want two.
Towing down in the winter is getting a little less enjoyable all the time, also, I don't knowing about towing a US insured and registered trailer with my B.C. registered truck.
We have thought about rental of a park model but we still like the ability of being able to travel and see more of the great south west. We usually only spend 2-3 months, Jan_ Mar. It would be nice to be able to run down in the car and spend some time in the fall and the spring. I guess I will have to give this a lot more thought. Thx
