Berk Hitch height

I know this isn't the towing section, but it is specific to the Berkshire.

I just measured the center of the hitch receiver after the air bags filled and it measured 16.75 inches. The pins on my toad, measure 22 and 1/8 inches. So I need a 4 inch riser. The problem I am running into is the measurement from the pin hole on the receiver to the back of the coach (in order to clear it) is 7.5 inches.

Has anyone else solved this problem with their Berk ?

Thanks,
Ken

Ken - I'm working this exact issue on my 390-BH right now.
Ground to centerline hitch = 16 1/2 " (aired up)
Ground to TV connecting pins = 24 1/2 "
Solution = 8" riser
Biggest question I have is how long must the shaft of the riser be to clear the tail of the MH.
Receiver on MH length = 8"
Length of MH overhang = 6"
Shaft length must be 15" (min) to clear the tail end
Working to verify all this today and will post answers.
With my Roadmaster Sterling All Terrain tow bar, I have a +/- 3" to work with to stay within operating limitations.

Regards,
Fred

It's the measurement from the receiver pin hole to the angle on the riser. Mine is 7.5 inches.

I had this same issue two years ago. Ended up going to a RV fab shop with my blue ox riser and had a custom extension made. The finished product worked out perfect for my toad (total cost was about $250). I think total rise was 4" to be perfect for my Tow vehicle (Chevy Silverado).

Etrailer a has an extra long receiver that I got and woks perfect. I was concerned about how much was sticking out and flex of the hitch itself, so I took the hitch off and welded a square tube from receiver up to another crossmember at the back end of the hitch. It made the hitch way stronger.

Can you give us the part number or brand of that hitch?

Now I'm thinking maybe an extension and then the rise.

I got an extension from Rtrailer and have been using it for eight years with no problems.

I have the same numbers for my 390bh as Fred. I was looking at getting the Road Master 8" rise adapter part number RM-048-8.
It shows a 7.25" distance from center of hitch pin hole to back of receiver tube.

I am also looking at the RM-048-6 which is a 6" rise, but has 9-1/2" clearance from center of hitch pin hole to back of receiver tube. Would bot be level, but within the 3" limit.
