Can't relate with you on the types of RV's your are talking about but in 2010 we downsized from 30-1/2 foot 5th wheel with two slides & a ton Dodge diesel dually to a 18 foot TT with one slide & a 1/2 ton Chevy pickup. We are very happy with the decision - of course we will soon be 80 so that may have something to do with knowing we made the right decision & still didn't have to give up traveling.
