We have a Primetime LaCrosse 329 BHS which is bigger with more cargo capacity than both of the units that you are looking at. Four rainy winter days with two kids and dogs are all we and the RV can take. The holding tanks are all full and the propane tanks are empty and my patience with dogs and kids is all used up (and that is when nobody is fighting about what video to watch after being cooped up). I think the biggest problem that you are going to have is winter humidity buildup in the RV and EVERYTHING being damp and moldy (sort of like a small live aboard boat). I would seriously reconsider this plan.
