My 2007 Wildcat sheared the 2 x 6 box tubing frame like it was paper. It happened on the rough Interstate in SC. Lippert said over 2 years old you're beat. Forest River blamed Lippert. Lippert kept me on the hook for weeks acting like they were going to help. Then they asked for MORE pictures. The next email was them accusing me of welding an 1.25" hitch reciever on the BACK of the 5er! The hitch had a Lippert sticker on it but they didn't believe me and said maybe Forest River added it. They just were making excuses. This happened in the dead of winter in NJ. I ended up realigning the break and welding it up. Then I fully reboxed the pinbox area with quality steel tubing 3/16" thick 2 x 6. I replaced the under lament with a sheet of 5x8 aluminum tread plate using 5/16 bolts, not screws. I also replaced the pinbox with the Airborne Airride.
Might be tough to see but that vertical crack is clear through both sides of that header.
The next two pics to show the flex loaded and unloaded. It moved alot! So much that the bike rack reciever was hitting the front cap on bumps.
I welded inside and out plus added gussets.
All new trim was sourced from a supplier in Indiana. The front end is proper now.
Topped it off with the airride.
Some people had better luck. It seems if you're out on the road they seem to work with you more from the stories I've read back when I was in your shoes. For me since I made it home they dropped me like a hot potato. Best of luck to you.
