One disadvantage to a bumper ball is you do not have the turning radius that you would with receiver hitch. Try GI Joes for a hitch, they have a ton of that stuff. Should cost around $100-150. They install pretty easy too. Good Saturday project for two people. Ya don't even need any serious tools like an impact wrench. My brother and I installed mine on my '92 Chevy 1/2 ton in a couple of hours.
