Looking at a google of a Roadtrek, I'd say the issue with Roadtrek is clearance more than 4wd too. Even with an SMB 2wd you don't have the spoiling hanging down. I met a guy at SMB West with just oversized tires on 2wd and it looked pretty capable.
That is something I worry about. If I can find a properly equipped SMB, I am likely to go with that, otherwise the Roadtrek, though it will be mostly a pavement-mobile.
