However, warolands trailer has a king pin extension already in place. It was likley standard equipment on his trailer.
Most trailers have an extended pin box as standard equipment and I'm pretty sure the Wildcat has one. It may or may not be sufficient for zero risk towing on a shortbed truck. Is the dealer suggesting a n additional extension of some kind??? Have never heard of such a thing, but???
Nor have I ever heard of a need for something besides a slider hitch if the trailer already has an extended pin box like the Wildcat has.
