I could have used this bit of information prior to ordering my trailer hitch from etrailer.com. That way I could have ordered a trailer ball mount from them at the time.

The inside top surface of the receiver tube on a Curt 13130 class III trailer hitch with 2 inch receiver tube when mounted on a RDX is 13 inches above ground.

For a trailer coupling that is 17.5 inches from the ground to the lower edge, a trailer ball mount with a rise of roughly 4.5 inches would be required for the trailer to be level.

Recommended dimension to clear bumper: minimum 9.5 inches center of hitch pin hole to center of ball hole when used in the "Rise" configuration.

 

Any specific ball mounts (manufacturer and model #, or link) anyone can recommend, assuming these specs are ideal?

I have a 2016 RDX AWD, Curt 13130 class III trailer hitch, and haven't purchased a trailer yet but will likely be buying the top-spec Harbor Freight folding trailer.


Thanks in advance!

 

Also, I already have the following ball mount from another vehicle, would it work?
