my tent was dropped about a foot from my pulley system and it warped one of my rails on the bottom of my RTT. It is perfectly usable and deflected maybe 1/8" over the 4' length, but I figured I would see what I could find. I have called the vendor I got the tent from to see how much replacement parts are.
Thanks for the help, the mcmaster site has some stuff that I think could work, at $15 for 4' thats not too bad.
