2009 montana falling apart 1 piece at the time

Each brand could be subject to problems. I feel your pain. In 2007 we custom ordered a DRV 5er that was exactly like yours. It seemed like every day something else would go wrong. We toughed it out for 4 years hoping things would get better....they didn't. Smartest thing we ever did was cut our losses and buy something else. Good luck. Rving should be fun not a hassle....
