Rear Frame Separating 2014 TM 2417 Sport

[Arrhysted]

My rear left framing is pulling apart from the body of the trailer and causing the rear shell to sag. Seems like I could just replace the nuts and bolts but I don't see a way to access the nut. Is it inside the wall of the trailer box, and do I need to cut into the interior wall to gain access?
I have attached pictures if anyone has any suggestions, I would appreciate it.

On mine, the nuts are captive inside the wall, so I just ran the bolts up engage the nuts, then tightened them down. I'm not sure how the nuts are captivated, so push the bolts up gently to try to grasp the first thread.

Can you turn these bolt heads or are the welded to the frame?

Thanks for the responses. I found the issue, which might be a rare occurrence. We had a prior plumbing leak that pooled in that corner of the trailer. After I cut away the interior wall I found all the wood rotted out and the bolts rusted tight. I haven't devised the ultimate fix yet but I have a feeling it's going to involve welding a support piece to the frame. Pics attached.

I agree Waverly, I know they want to save weight but I live in Seattle . Another concern is, I know the rotted wood continues up the trailer side, I just don't really want to cut into the interior of the trailer itself.

I would replace that rotted wood with marine grade plywood and laminate the layers of plywood with epoxy resin. Highly recommend "West Systems" epoxy from West Marine.

Cut the pieces to size. Laminate the pieces together then drill your holes. Then coat the entire piece with epoxy, let set for 1/2-hour, then coat it again (it's called wet-on-wet). Let it set for at least 72 hours before setting it in place and bolting it together. Fill any voids with expanding foam and let expand for 24-hours. Trim and you're ready to put it all back together.

That reminds me of when the fiberglass deck of my yacht leaked and the wood core rotted. I had to tear up the entire 45' length of deck and do the above. Not fun on a big boat.
