Permanent fix for Coroplast underbelly

Hey, you have the same trailer as I. The first time I pulled mine down, I cut it into three sections. At one split, I added an aluminum angle spanned between the frame I-beams. At the other I added a metal strip to one end of the cut piece to have something to screw into with the other piece. Yes, it is a pain to pull down the iron propane pipe, but a must. When everything was reinstalled I put strips of Gorilla tape over the split lines.

I've actually had the whole thing down three different times. The section over the axles is the hardest to reposition.

This thread should probably be in a different forum.
