I have a 32 foot goose neck enclosed race car trailer. The goose neck on the trailer is height adjustable, but I'm looking for some guidance as to the elevation. right now, empty or loaded, the trailer does not sit level attached to the truck. It rides tilted towards the back axle, proof is that the back tires run hotter than the front. Should I adjust the hitch so that the trailer sits level when attached to the truck? Both axles have brakes.
