2022 Grand Design Momentum 397THS-R w/ Lithium & Solar

LOCATED IN TUCSON ARIZONA!

If youre looking at a Momentum, you probably already know that theyre nice campers, but RVs are rarely ready to go. This one is, whether you are looking to go on vacations, overnight at a Harvest Host, stop in a friends driveway, or live in it full-time. We have lived in this rig full-time for three years, which means we have improved it, & maintained it. We are going to try a Class-A next, so as a result, this rig is for sale. We move this rig about 40 times/year, so all of the systems & seals get regular exercise. Camper mileage was 24,000 miles in Oct2025.
