In the world of RVs, unforeseen challenges can emerge. My team at California RV Specialists recently encountered a concerning issue while maneuvering a Forest River Wildcat around our service yard.
The owner of the unit had been unaware of the potential danger lurking beneath the surface—pin box frame flex.
Join us below on YouTube as we delve into the details of the frame damage discovered and witness the meticulous repairs carried out by my crew.

The discovery: Signs of frame flex
As the unit was being carefully moved through the yard, we detected subtle signs of pin box frame flex, a concern that could jeopardize the structural integrity of the entire RV. We investigated further.


We embarked on the task of repairing the frame damage. The repair process is detailed, offering insights into the careful assessment, precision welding, and reinforcement techniques employed to restore the structural integrity of the Forest River Wildcat.
Quality assurance: Ensuring roadworthiness
After the repairs were completed, the unit underwent thorough testing to ensure that the frame damage had been successfully addressed. The video provides a glimpse into the quality assurance measures taken by my team to guarantee that the Forest River Wildcat is not only roadworthy but also meets the highest safety standards.
This video not only serves as a cautionary tale for RV owners but also highlights the importance of regular inspections and prompt action when frame issues are suspected.

Great detective work Dustin! I have a class A MH – however, thanks for the heads up and something serious to be on alert for. Have you found any frame/chassis problems like this on class A’s or B’s – new or old?
Doug,
No we haven’t found any issues so far with chassis side.
This is NOT new to Forest River. I had a 2004 Cardinal 5th wheel, which is a Forest River product, that had a major pin box failure in 2006. My local RV repair shop contacted Forest River and was told that it’s NOT an uncommon problem and that Forest River was aware of the problem. Forest River sent repair materials, directions and paid for almost all labor to fix it.
Thank you for the reminder that good techs pay attention to everything, not just the problem that caused service to be scheduled. Downside is that the price for the service visit can increase markedly beyond the naive initial estimate. Paying a large bill is painful, but the added safety is comforting. Have a great day and safe travels!
