Trailer Wall Covering

[Rotax_Kid]

I have a nice new 7' x 27' MTI that we purchased a few months ago. THe trailer came unlined and uninsulated. I want to line the walls and will insulate with rigid white beadboard. Having some trouble trying to figure out what to line the walls with that is relatively inexpensive. I initialy wanted to use white puckboard, but 1/8" is nearly $50 a 4' x 8' sheet.

What is everyone else out there using? Trying to stay fairly light..trailer empty is light and pulls real nice. Don't want to add a pile more weight to it.

What about just using a thin plywood and painting it white? Sheet alum is light by pricey.

Ya just 1/4 inch good one side plywood works good. Paint it up. Wont expand and contract like puckboard will.
I tried some white wall board once and it did the same...moved around alot causing a mess.
