Just a tip: Upgrade trailer/camper bumper caps to hitch pins. Keep your sewer hose secure and dry.

Easy and handy upgrade for a travel trailer, pop-up, or 5th wheel with the dump hose stored in the bumper. The little caps eventually fall out, and then so will the hose. Thus, why you occasionally see dump hoses laying in the ditch. Just drill a couple holes and use clevis pins instead. They won't fall out, and they allow plenty of air circulation.
