The reason your hitch is high is that Fleetwood builds the RV with the slanted rear to help keep it from "tail dragging" when on an incline due to the wheelbase.
Most of us Bounder owners have to use some size of the drop-hitch, depending on the height necessary to keep the towbar level. We tow a Jeep Wrangler (stock) and our drop hitch is 8".
Most of your towing questions will get better responses in the Toads and Motorhome Towing Section.
Toads and Motorhome Related Towing - iRV2 Forums There are lots of existing discussions of base plates, tow bars, braking systems, etc.
