Here is the defect I have found. There is a defect and it cost me some bucks to fix before I figured it out. Rain water runs along the trough against a clip on the corner covering the trim holding or covering where the roof is attached along the top of the camper. There is nothing inside the clip to prevent the water from entering into tha gap around it and from there, once iside the clip, into the camper. A manufacturers defect which rotted out the front of my camper. They should have canned the brain dead engineer who designed it. They should pay me the cost for half the camper for the amount of money and frustration this has caused me. And unless they do, I will never buy another Forest River, Wildwood, Salem or whatever camper or off brand camper this manufacturer makes again!
