question on on hitches on the back of fifth wheels

I've looked into this and the standard bumpers on rigs are really not up to par for this use.

I have a single receiver on the front and I heard of one guy who put two on the front and had a carrier that would fit it.

Having said that I'm in the camp of adding more frame work to the back of the rig so I can carry it without fear, saw a video of a guy who repaired a bumper that failed with two bicycles so the stock set up is not rated.

YRMV.
