Anyone here have a Class B van? Happy with the choice? I'd likely want to drive around the Western US, maybe do a Mid-West or South-East trip, too, but the big goal is an all-summer Alaska road trip. Thoughts on how that might work? I'm a nube to RVing--never done it before, though we do know Alaska fairly well, at least the stuff along the main beaten path between Seward and Fairbanks. We'd want to go a bit afield, and it seems a Class B may be the best option for that.
