Hi all this is my first post, i own a 2000 harley f-150 w/ after market under rail liner and (I THINK) factory rail caps..... i'd like to install a Pace Edwards bedlocker electric tonneau cover..i'm not sure if it can install over the rail caps or do they have to come off ..anyone out there had any experience w/ this product...i was going to purchase a undercover but i might have to load an occasional tall item and i have no place to store the removed top. thanks for any info pro or con...
