You nailed it, move them out is the game. We've had TTs and 5th wheels for a while, we purchased a 351DS about 6 months ago. I noticed a front end alignment problem. Asked around, most said to take it in regardless, because almost all MHs need that done. I call the dealer, they have to hunt and search for a place, it took months to make the repair. Most dealers don't have facilities to do the most minor repairs, and if they do...be prepared to wait, a long time. Word of advice, document everything, not just in writing, pictures, videos if necessary, dates, problems. Not everything has the same warranty, just like owning a home. Document repairs, keep all dated paperwork as well. Traveling around is super awesome, but something always seems to go aery here or there, most of it small stuff, but occasionally the big one hits, being prepared is half the battle.
