Great product with lots of options for using it!

We have a Jack-It mounted on an RV frame, an adapter mounted on a boat trailer and a hitch extension on a third trailer. This allows us to move the arms to the trailer we need to carry bikes on, without needing 3 separate complete racks. I think we’re all in at $250, and the hitch extension is universal. This not only saves money but saves space and the Jack-It is one of the only racks that would work in our application.As flexible as the system is, the finish leaves a lot to be desired. Parts start to rust after the first rain. Also, the bolt / hitch clip method of securing parts is not a bright idea, though I understand why they did this.Regardless, we’re happy with the purchase as it fits the bill.
