Hi, Need to know if anyone has added Class III hitch to rear of 98 Jayco. Trailer does not have a rear bumper and frame appears to end about 30" from rear of trailer to accommodate fresh water tank. I want to add a generator such as an Onan Juice box but need advice on how to attach the receiver hitch without making a low hanging device that will bang into high slopped drives or curbs. Any suggestions will be appreciated
