How Close to Top of Flat Bed Does Ball Need to be For Demco Recon to Fit

Question:

I have a Dodge RAM 2500 with a Knapheide KNPPGNB868R flatbed. It has a recessed gooseneck ball the ball is 3 2/16inch tall, and there is 1 1/16inch gap to the flatbed surface. This solution looks perfect for my need, except there is some mention in the DEMCO Q and A that maximum gooseneck ball top offset is 13/16 If that max is true, is it possible to use a washer or similar shim to raise the ball top by 4/16, i.e. 1/4, or are there taller gooseneck balls? I have tried the Convert-a-ball gooseneck adapter, and: - towing does not handle that well trailer does some oscillation, even in good driving conditions - I learned it stresses my 5th wheel frame leverage looks/feelsinch wrong may void the frame warranty etrailer does not recommend this as long term solution but didnt tell me when I called before I bought it Also, I prefer to not permanently convert the 5th wheel trailer to a gooseneck I may not have this truck long term

Helpful Expert Reply:

If the gooseneck ball of your truck is removable and you could find the correct size spacer so that your ball sits and the needed height for the Demco Hijacker part # DM8550046 of 13/16 inches this would work great. Some balls are attached with a nut that has plenty of threads which would easily allow for this so you'd need to check to be sure.
