I made a bike rack out of 2x6s to put my bikes on the top of my camper. It worked well and made it 300 miles with no big issues. The small issue is the ratchet strap rubbed the paint off the top corner of my camper down to the metal. The straps also rubbed some paint off my bike. The red from the straps now shows a bit on my camper awning bag. Does anyone have a solution for this? I'm wondering if a better pair of ratchet straps would help, or putting some felt carpet on the corners and the bike. Any advice would be helpful. I attached a picture of my rack.
