I'm using the Pull-Rite Super Slider with under bed rails. When removed, it leaves only 4 half dollar sized holes in the bed
. The hitch weighs around 250 lbs. Their propaganda said "easily removable" . . . Ya Right!!
. . . Easily removable for two guys and a mule maybe . . .
I've taken it out once by myself (and put it back in). Yep, it can be done as a one man job . . . but I wouldn't recommend it!
Seriously, with one or two other people to help, the removal and replacement would probably be fairly easy. The process is simple.
