I have a 2005 Sierra T28FB toy hauler. This morning, I noticed the fuel line for the generator was unsecured where it crosses the trailer behind the rear axle.
When I got underneath, I also found that the crossmember behind the rear axle was broken. I found that the crossmember behind the fuel tank had the same issue.
As can be seen in the picture, they appear to made from two pieces of angle with roughly 3/16" steel rod welded between. The rods are mostly broken, those that are not broken are bent and on their way out.
I have considered two options for repair:
1. Remove the crossmember and replace it with an I-beam.
2. Weld in additional pieces of angle, vertically, to do the job of the former x-bracing.
Wondering if anyone has had similar issues and I'm also open to other ideas for repairing this issue.
