I've given it serious thought. We have a 38 DP. Many of our favorite state parks have few sites that can fit us and they book up 11 months out.
A class B would be a weekend machine and open up so many more spaces.
We love St. Augustine Anastasia SP only has like 5 spots that we fit in for instance.
We could also use a B or van conversion for events, light tailgating, etc.
I don't have a tow vehicle but if I sold the DP in a few years I would go back to a TT and could see myself with a 22 and a 30.
