A reciever hitch can be used under the Hanna bumper and can easily be installed and removed without having to supporting the bumper. I recomend towing with the reciever hitch, it is the safest way to tow a trailer behind the 80.
For me the main issue using the Pintle hitch is that it places the trailer ball to high for most trailers, street trailers.
The hitch that has the 2 inch reciever passing through the main structure and not under the main structure of the hitch has the same clearance and the Kaymar, while having the option to remove the reciever hitch if need be for clearance.
