If the Burro interior is similar to
Uhaul, [never been in one] what we did on our
Uhaul is we found at Lowes and Home Depot some indoor/outdoor carpet that is a polyester fabric made from recycled plastic bottles, color is gray. It is very
light weight. We glued it up with Weldwood contact cement. Cut it to size first, then used a small
paint roller and cheap brush to apply the cement to the back of the carpet and to the area in the trailer. Let it set for a few minutes and stick it on. So far it's stayed stuck. I did first go over the area with a
paint scraper and small sanding disc to remove any old glue that was loose, and at a couple places below the front window where the inner shell was not tight to the outer shell I used bondo to smooth out that area. If you apply too much contact cement to that type thin carpet it will show through. The carpet comes in a 6 X 8 foot roll and cost around $20. Not sure if the carpet that was in our trailer when we got it was the original, but whoever put it in did a real sloppy job installing it, with glue exposed all along the edges. I cleaned that off with Walmarts brake parts cleaner on a rag. Brake clean is my favorite stuff, but it can damage some
paint and plastic. On another note one of our kids spotted a Burro 13
for sale right down the road from their house, checking on it today.
