The problem isnt so much the cap as it is the fact that the plastic bed rail caps compress and let the cap sit too low after a little time on them. I had to shim mine up in the corners a little bit with some pieces of ABS. I also did a little bit of cleaning up the two rear and drivers front corners on the inside of the cap with a file.
I have the 100xq BTW
