upgrading the Hitch from class 2 to 3 on my motorhome

This is a "Hidden Hitch" (brand) that is rated at 5000 pounds or 6,000 while using a weight distribution system. It will work with any frame width from 30 - 46", so might also work on trailer frames as well as your motorhome.

RV hitch - 31" to 46" frame width

They have other models, you can search for them. This is the one I was considering for my 2002 E-450 chassis. But I may still have a custom hitch built. Like you, I have a very short chassis extension, my overall length is only 23'.

I can attach to the Ford frame, and do anything I want if I attach there. Then run a 12" long 2" receiver holder back to the bumper (so it will not stick out or be way under the bumper). My plan includes 3/16" thick flat stock to hold a 3" OD cross member, and 2.5" OD (2" ID) bar going back to the bumper. I know a certified welder, and he can built it for me. I have a 22,000 GCVWR, and the V10 engine with 4.63:1 rear axle ratio. My GVW is only around 8,000 pounds or 9,000 ready to go camping, so I am also a lot lighter. My plan includes a 10,000 pound trailer and 1,200 pounds of hitch weight. The E-450 that I have has a rear mounted wheelchair lift, and 12 seats.

Good luck on your project.

Fred.

Are you going to flat tow, dolly or trailer?

You really should ask the manufacturer of the RV. Odds are they will say "no."

My guess is they put the Class 2 hitch on it because that is all they are willing to guarantee the frame extension for.
