Hitch rails in the pickup bed are a pain when the hitch is off and you are hauling bark, crushed rock etc. (material gets in the slots in the rails) or trying to roll an appliance or other heavy object over the rails. Has anyone ever seen any sort of cover that fits over the rails to alleviate either of these problems....or do I have to make my own?
Thanks!

 

That's one of the major benefits of the Companion 5th Wheel Hitch... no rails or anything left in the bed when you don't need it. My father has one and it's great.
