That is some excellent information for my situation rvhippo. Especially the parking space size.
Over the past 6 months we have been taking meetings within a 5 hour drive of Memphis so we can get back for school on Monday mornings. A lot of the McDonald's and other small places that we stop at have only diagonal parking against a curb. A larger RV or any vehicle towing stuff has to park sideways and take up 5-10 spots. Wanting to avoid that is a small part of my desire for a smaller RV. The information you give about parking sizes seems to indicate that no matter what I do, it's going to be a problem. hmmm
A Class B towing a TT would be ideal. It would give us the RV features while driving I'm looking for while giving us storage and a place to stay that would be cheaper in the long run than a hotel. But as you pointed out, Class B's are very expensive.
Originally, I was looking at a Dodge Caravan with the swivel seats and table. That morphed into a small RV. Now I may have to go back and rethink my original idea. We lose the on the road bathroom ability and a few other on the road perks but gain a cheaper form of transportation at locations while still getting the nesting ability.
How long/ how much work does it take to go from driving to occupying a travel trailer? Could we pull into a rest stop or truck stop (or Wal-Mart parking lot), get out of the van, walk into our TT and go to sleep?
