How many people that have a slider hitch have used it and how often? Short bed trucks. I hear trailers are made so you don't need it but just wondering who has used and under what circumstances? Tho...
Most newer fivers are "cut" in the front so that they won't hit the truck when cutting really sharp. However, you could go a year or two and never have to slide your hitch and then one day you get on some uneven ground.
If your FW leans a little while jacking it into a tight camp site you could find that you do need a slider.
