Rear bumper box?

[bclinton]

Curious if anyone has attached a light duty bumper box on top of their MH rear bumper? I need something back there to store about 30 feet of coax cable and maybe a tool that my verizon celll booster will be using when I extend the pole next to my ladder. The cable will be in heat resistant wire loom that is zip tied to the frame rail and will come out behind the bumper. I am trying to avoid a perm install of the pole and plan on extending it with the antenna when I camp and taking it down when I leave. Minimal weight will be in the box and looking for something weather proof.
