I'm surprised no one has mentioned this yet, so I'll chime in. You mentioned you're not planning as much traveling as sitting for 4-6 months at a time. If that's the case, I'd go the 5er/truck or TT/truck route vs. a MH. You'll get more space with less or more manageable maintenance. Plus, I read all the time that MHs need to be driven. Ours sits in storage for several months before we're able to travel, so DH has to make a concerted effort to drive it from time to time just to "exercise" it. Yes, your big truck will be your daily driver vs. a smaller, cheaper toad for the MH, but that should be offset by the cheaper maintenance for the 5er/TT.
Good luck with your plans. Hope it all works out nicely for you.
