As others have already alluded to, you don't NOT want to install a bumper mounted receiver on a trailer. It's NOT a matter of "if" it will fail, but "when" it will fail. The failure point is the thin sheet metal of the bumper.
More appropriate options are to fabricate and weld a hitch directly to the frame rails of your coach. Etrailer sell a few that are very universal to a trailer application. This is the one I had installed:

Your other option (if your hideout is a travel trailer) is an elevated bike rack that bolts on to the a-frame. I bought and installed
this one last year. It performs better than a rear receiver hitch bike rack as there is more stability and less turbulence at the front near the tongue. My $$$ bikes thanked me!
