How to use the rack? Well, I removed the spare tire (carry it in bed of truck). Next I purchased a high quality black composite truck bed storage box and bolted it to the rack. I store lots of items in this storage box, water hoses, chocks, leveling blocks, are just a few of the many items I moved from the storage area in the trailer to the rear storage box.
I also carry 2 dump hoses that can be connected together to lengthen the distance I can park from the campground sewer. I have 2 gray water tanks, one for rear kitchen and a second for the bathroom. Two hoses really comes in handy now an then as I position the trailer on the pad. I made a 2nd sewer hose holder and bolted it to the underside of the rack. It looks good and is extremely handy and I don't need to store the second hose in a garbage bag or plastic container in the trailer storage compartment.
So there are several good uses for the rear rack if your a bit creative. Go for it!!
