You can get an auto slider....it will reposition while maneuvering
Or you can get a manual slider that you have to 'unlock' for maneuvering
Traveling forward is usually not a concern until you try to make a 'U' turn or a very sharp turn.
Course this also depends on 5vr front cap design....flat or scooped
Flat is more prone to whacking truck cab during tight maneuvering
And also pin box.......short box or extended box
Extended places front cap of 5vr farther away from truck cab
Short box more likely to cause issues
Short bed truck/short pin box/flat front cap on 5vr........slider
Any other combinations.......maybe :B
Auto slider......hookup and forget it cause slider will reposition when needed
Manual slider......you have to remember before you hear that crunch
