Trailer Walls - Want to finish, what to use?

[snowpromod]

Hi,
I am picking up a new/used trailer and want to finish the interior - we tried the 1/4 white board from Home Depot and it sagged terrible and looked terrible. I would like to do this one and have it look half decent, what should I use?? Thanks

I helped a buddy finish an interior in his trailer, we used dry erase board, then covered the seams with a stained piece of wood strap, it looks great plus if you don't have a piece of paper just take your dry erase maker and write on the wall.

Try FRP, fiberglass reinforced panels

1/8"-4'X8' sheets of teflon. Kind of expensive but very durable if you want the trailer to last for awhile.................
