New to forum, just bought my first 5th wheel TT!

We had a bighorn Silverado by heartland with the back bunkhouse with opposing slides. We started getting fractures in the upper corners of the skin. Heartland wasn't much help so we traded it in. Just keep a look out, maybe they fixed the issue because ours seemed like a first run model. I would be cautious about putting wheels under the frame in rear also, especially after what I saw happen to our skin without added twisting.
