After an unforgettable year of full-time RV travel, weve purchased a home and are ready to pass our Montana Mountaineer on to its next family. This RV has taken us all over the country, and weve invested heavily in keeping it reliable and well maintained. We have maintenance records and major repair receipts available for serious buyers.

If youre looking for one of the best family fifth wheels ever built, the 350QBQ is hard to beat. The standout feature is the private rear bunk room, which feels like a true second bedroom rather than just a few bunks. It offers multiple sleeping areas, built-in storage, and its own half bath, giving kids or guests a space thats truly their own. Its one of the reasons this floorplan remains so popular with families.

A Few Things to Note

The front entry door could use adjustment, though weve primarily used the rear entry door without issue. The drivers side rear corner had a professional cosmetic repair after minor contact damage and has had no leaks since being repaired and resealed. Three ceiling puck lights on one side of the bunk room slide are currently not working.

Were only selling because weve purchased a home. If youre looking for a clean, well-maintained family fifth wheel thats ready for its next adventure, wed love to answer any questions.
