I originally said about 10 years since we did the Alcan (sorry) but have figured out it has been 16 years. We took a brand new 1998 Winnebago Adventurer up and limped back to Forest City with a broke RV. Sagged out springs, broken generator pipe and the list went on and on. This was driving very cautiously and respectful of the road conditions. Said we'd never do it again - now we are thinking about doing it again with a 2015 Southwind. Hope you can understand our concern.
