I know someone who bought a used trailer and he epoxy painted the trailer deck to clean up the appearance inside. Eventually the sticky rear tires started to pull bits of paint up on hot days so he just covered the tire track locations front to back with 2 strips of diamond plate.

Did you make your ramps out of 2x4s?

is Trusscore and where did you buy it?

Trusscore is a pvc based material used for walls and ceilings. I bought it at the local Wimsatt building materials store. It comes in 16”wide panels in lengths of 8’, 10, 12, and I think 20’. It’s not cheap but I liked the install method and some of the other features .

The ramps are two 2x10’s wide and 2 high. I needed a minimum is 2” rise so 1 row wouldn’t do it and I did both sides as a posed to just the driver side because I jus like the car sitting level
