We are former owners of a
Uhaul camper which is almost identical on the inside as a
Burro. Also as a former member of the
Uhaul facebook group we have seen many different methods of covering the bare
fiberglass ceiling strip. On our
Uhaul we just used a strip that we cut from a piece of carpet that both Lowes and Home Depot
sold. The carpet is indoor / outdoor made from recycled plastic bottles, size may have been 6 X 9 feet, and was fairly inexpensive, maybe about $20. We put it up in two sections with contact cement but you have to be careful to not use too much cement as it can soak through. Simple and cheap. But if you want to be more fancy or elaborate I suggest you join that Uhaul Facebook group and search there. Some owners had some great ideas. They welcome
Burro owners.
