ive always just used the ramparts kits where you put the aluminum ends on a couple 2x8's. I know some people that have the ramps that replace your tailgates. those are nice as the use your existing tailgate hing points and are wider/more stable than 2x8's
Why do people not respect us as they do other tradesmen? Because every Tom, Dick, and Harry doesn't think he can be a plumber or electrician!
