Ours won't fit in the bumper with the fittings. It is more convenient (my opinion) to have all the sewer stuff stored together. We have a rhino sewer hose. We scrunch the slinky to it's shortest size and connect the fittings on each end to each other the store in the front compartment of the basement of our fifth wheel along with the clear connection and other sewer fittings. If we had a TT with less outside storage, I would probably do one of the fence post mods just so the fittings and hose could be stored in one place. I guess it is really just a matter of preference.
