Well I took it off the trailer today as promised. Found a super easy way to get it off. Just jacked it up fairly high. Then put some milk crates under it. lowered it down a bit so the trailer separated from the bubble. Then slipped some tie down straps between the frame and the fibreglass bubble and lifted it up using the rafters in the garage. dropped the trailer puled it out. slid in a big moving dolly and done.
Now what did i find.... Every screw under the dinette was toast. As in not attached to the trailer. So the only thing that was holding it to the trailer was the two big bolts in the front. So this might be leading to the cracks. I also found a really big crack that was hidden by the trailer. Just where it makes the 4"rise. It is on the passenger(door) side.
So it looks like I will have some major fibreglass work cut out for me.
Trailer will be off to the shop for a new axel, the strengthening plates, sandblast and paint
