We experienced the "7 year Glitch" on our way to Alaska in 2011 in our '04 Southwind. Developed a leak in the rear passenger side corner and the rains would not stop long enough for me to dry things out to caulk and patch. I never located the actual leak, just put enough caulk in enough places that it stopped. Blew or burned through both exhaust donuts near Fort Brag CA, as close to no place for RV service as you want to be. Made awful noise climbing the hills. The interior cabinetry, never the best, began to come apart requiring constant attention. A year later it was clear the interior needed to be completely redone and the WH chassis had 105,000 miles so we decided to trade it in on a DP.
I have 4 1/2 years to go, however we are presently in Red Bay hoping to prevent some of those glitches from happening.
