Need help from experienced 5th wheelers

[MIMF]

Hey gang, I roll up the bed-rail cover, take the tail-gate off and set it on a blanket in the garage. Then I use a bungee cord to hook it to the rear rail that the 5th wheel pins into and plug it in under the bumper. It is long enough to lay on the rubber bed mat and goes down over the bumper. No rubbing or chaffing on anything.
