Bikes on Back?

Anybody put a hitch receiver on the back of their Elkmont?

All I want is a small 1.25" hitch receiver for a 2 bike rack.

Have seen 2" bolt on receivers for 4" bumper bars but nothing for the Elkmonts 2" bumper.

Hanging that weight off the bumper will not be a problem for the trailer, as I've still more than 300# below GAWR. And it would be beneficial to remove some weight from the tongue and truck as I'm exceeding it's GVWR somewhat.
