I've an older Thule utility trailer (from back when Thule made utility trailers) like this one:

The original bed is pretty much shot so I need to replace it. The bed itself is 101" x 59" x 1/2" thick and is made of what appears to be plywood with a thin layer of dimpled, rubber-like material on the top surface. It's supported on all edges and by 2 heavy u channel ribs that run from front to back (along the long dimension). The thing has hauled many, many tons of "stuff" from gravel to equipment and machinery to lumber. It sits outside year round, uncovered.
I haven't been able to find any suitable sheet material that is big enough to replace the bed in one piece. So my current plan is to special order two sheets of 4 x 10 x 1/2" marine ply and place it so there is a single, long seam over one of the supporting ribs. Then I plan to apply a couple coats of roll-on truck bed liner. It looks like I can also get 4 x 10x 1/2 MDO, probably a lot cheaper than the marine ply. I think the marine ply might be better but the MDO might be good enough?
Anyone have a better idea for material or see any problems with this approach?
