So far we have installed a new floor, new fridge, new furnace, new hot water tank, re upholstered the couches and had some custom curtains made. All our work was done by Blue Moon Caravans in Missoula Montana. As well, we had it checked out top to bottom and no issues were found. We also had some plumbing and electrical upgrades done. The trailer was stored indoors for over two decades and was in excellent condition when we purchased. Our trailer is middle bath, so no issues with rear sag thus far. Knock on wood, she's a beauty!!!
