The frame of my trailer sustained damage due to flexing from poor design. I was lucky and noticed some loud noises when transitioning weight to the king pin on the truck. A lot of creaking and groaning. Because of all of these noises and what I had read online, I had the trailer inspected. The inspection found the frame moving within the structure when the weight transitions from the stabilizers to the king pin. Additional damage was a crack in the structure that holds the wall to the frame and many bent gussets that are designed to give the structure strength. This design is substandard. I understand the whole thing is designed to work as a whole to provide strength, but there are weak areas in this design. First is the use of lag bolts into a soft wood as a method of connecting the frame to the wall structure. This needs to be into metal or aluminum allowing the use of bolts and a thread locking compound to prevent loosening. Lag bolts into wood on a structure designed to withstand dynamic movement of towing is inadequate. This will always loosen over time transferring the load to other areas of the structure and the damage many are seeing. My trailer has been repaired, but I’m not sure if the new gussets and additional lag bolts will be enough because they are still using wood as a structural component. My trailer is a 2020 and the 5 year warranty will expire in September. I’m not sure where I will be after that when the next repair comes. I don’t have a lot of pictures because I was out of town when they did the inspection. You can see the break in the wall support showing that the wall was moving after is separated from the frame. The pictures show how this bent the gussets that are designed to give the structure support. Like I said, I saw this problem online and asked for in inspection before I had real problems. If I had waited, the damage would’ve been much worse.
