I used one for almost 4 seasons, 3 seasons with my 5'7" bed F150. It is important to check the torque of the turret bolts every few tows as they tend to loosen. This summer, the back two turret bolts sheared off and I had to take have a machine shop drill them out. I replaced all four with slightly longer grade 8 bolts as they missed a thread or two from going all the way through the nut.
To be fair, the sheared bolts may have been due to an accident where I dropped the fiver's passenger side wheels off the road on a narrow trail and that tipped the fiver about 15 degrees.
I finally had to replace it with a MorRyde as it kept the fiver nose too high with my new F350.
