My new GMC2500 truck has a 2.5 inch receiver, and my old truck had a 2 receiver hitch. My horse trailer has a 2" bulldog coupler. I used an 8 inch drop ball mount before, but will need to go to six inch drop for the new truck's ball mount for the trailer to sit level. Trailer is a 2 horse that weighs approximately 3000 lbs unloaded, and about 6000 lbs with horses and tack.
I have two questions for you experienced haulers.
1. Move up to a 2.5 inch ball mount, or use the sleeve insert for a 2" mount that came with the new truck?
2. Should I spend the money on an adjustable ball mount, just in case I ever need to tow a different trailer, or stick with a fixed-drop ball mount? If I go adjustable mount, are there specific things to look for?
