How water tight is the f1??
It held dry on a medium rain on one day. Washing after TRR it got a little water in the bed but I think it was the tailgate to bedside seams. Nothing leaks through the F1. The rail is a channel with a drain tube in case water gets sprayed under rubber seal edges.
So far I like it alot. If you need to take off, it's only two large knob type bolts. Rails are three rail clamps on each side 9/16 socket.
