Some good advice. I will check into the front being higher than the rear. I have a BOSS flip ball gooseneck hitch and mounted it where the directions said for the short bed I have. I can't remember the exact number, but I can believe it's close to the 4-6" ahead of the rear axle. The trailer is pretty close to my toolbox when hooked up. The BOSS hitch is appears to be exactly like the B&W flip ball. I compared mine to a buddy with a B&W and I'd say it's an exact copy. Only difference is I can't store my ball upside down in the holder, I can only remove it completely. Maybe next time I will try putting the truck farther ahead on the trailer. It is squating the truck pretty good, so I figured that was far enough. I also think maybe I should shim the ball in the socket. I did hear it clank when going from forward to reverse.
I don't get much bouncing or squating of the truck when I hit bumps. That feels good. My biggest complaint is the "jerking" for and aft.
