Originally the left rear cab edge of my 2500 HD GMC and the left front edge of my living quarters trailer had about 2" of interference. That is no longer the case because the cab/trailer interference area has gradually self clearanced
{The truck cab is bent, no damage to the trailer.]
It sneaks up on me, only touches under unusually tight turn when the ground is not level.
So, before I knock a hole in the cab and break the back glass, it is time to make an adjustment.
The truck is equipped with a turn over ball hitch and installed per the manufacturers instructions. It is a 2006 GMC HD Duramax, crew cab, short bed. The hitch ball needs to move rearward about 2" or some kind of extender for the trailer. [This is a goose neck hitch system]
Does someone have a solution?
