My brother in law had a 1999 K-Z, don't remember the model but it has Wil-e coyote on the front...
His started separating at the front right corner, at the bulge. He didn't have time to get to it over the winter. It turned out to be about a good 3 foot section. He applied duct tape to it and used it once more. It wasn't getting any better...
Anyway, he was driving up to Duluth and the entire wall separated from the frame - from the front to about 5-7 feet back. He had replacement insurance on the RV, and it was deemed a total loss. Wish I had pictures.
Delam = bad
