This question was just asked in the last couple of weeks. We had a
Uhaul camper which is almost identical to a
Burro. We used a thin carpet that is made from recycled plastic bottles. Got it at Lowes or Home Depot, size may have been 6 X 8 feet, put it up in two pieces with contact cement. The
Uhaul camper Facebook group has all kinds of ideas for the ceiling strip, and they welcome
Burro owners there.
