Yes, it does! The center of the king pin of a 5th wheel trailer needs to be centered over the rear axle. If you had the hitch and the pin weight behind the rear axle you would unload the front axle and make braking and handling dangerous.

The Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter for Recessed Ball item # DM8550046, you were looking at, is designed for flat bed trucks with recessed wells. The top of the gooseneck ball must be 13/16" or closer to the top of the truck bed for the hitch to install.

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…
