What is the correct height for figuring drop for a hitch? I Know the trailer should be level when measured, but I have a load compensating Escalade. My figures say it shoul have an 8" drop hitch, but my 4 x 4 gmc dully only needs a 6" drop. The receiver on the caddy is almost a full 2" higher then the truck, whic did surprise me. But an 8" drop hitch still seems like a lot.
