I'm going to buy a class III hitch for my 1999 Chevy K1500 pickup. I want to get a bolt on that sits right behind the rear bumper. The truck has P265/75 R16 factory size tires on factory rims, no lift kit but does sit pretty tall compared to a 2WD model. My question is how much drop should I get on the ball platform for general towing of trailers, rental equipment etc. The reason I ask is that I don't own anything that I tow I just need it for when I do have to pull something.
Thanks Brian
