I know everybody uses Keder or a version there of, but..I don't see anyone designing they're own rail.
I made one from a piece of 1/2" PVC pipe I had around for my old trailer and about to do something for the truck camper now. I like the concept of Keder type rails and was hoping a few others might have come up with some more options of the years. Maybe I'm nt addressing google correctly or far too many folks have bought there way to the front of the pack (which seems to be happening a lot lately).
Anywho.. Have or have seen any other ideas beside the cut a slot in a pvc pipe? Would love to hear about it!
