I am making two brackets now for installing a sewer hose storage tube behind the gray water tank. I will take pictures if anyone is interested. The brackets are 1/4" x 4" x 4" aluminum angle 8" long. I mounted it with hex head self-tapping screws (3/8" head). Drill three 1/4" holes in a triangle pattern in the aluminum angle that will mount to the frame and two holes in the other part of the angle the will mount to the Valterra Adjustable EZ hose carrier. Cost: Aluminum angle $20.65 w/tax and six self-tapping screws plus 4 1/4-20 bolts nuts and flat washers were $3.19 w/tax at my local hardware store.
