Frame issues

[sandusky618]

I have a 2017 Vengeance 420v12 that I bought new in 2018. I was washing my camper and just found delanination at the corners of two of the slides. I took it to a RV/Camper repair shop and the gentleman over the repair shop said he had seen this before on some other Forest river campers last year. He said that it was due to the frame flexing to much causing the walls to bow and causing the wall to delaminate. Just to make sure he had more than one employee give the camper a once over to verify what he was seeing. Has anyone else had this issue? Forest River and insurance say that there is nothing they can do, I am waiting on Lippert who makes the frame to get back with me but I am sure they won’t do anything either. If anyone can help it would be appreciated.

Unfortunately theses big toy haulers are known for this. If any water leaks it loosens it up and with a fully loaded 18k trailer bouncing up and down the road its a recipe for disaster. I have a 2020 and have a small spot near the front cap with the same problem. It can be fixed but it's a big job and not many people want to mess with it. There are some good videos on YouTube that explain what's going on and how to fix it. First I would reseal the entire trailer. These things leak from day 1. Good luck.
