Just bought a new Keystone Cougar! What else do I need?

I'm well aware of all of that. It's one of the reasons I spent $3,000 on a ProPride hitch. I've read about the capabilities of my truck and different trailers and towing and payload capacities and tow ratings until my eyes were bleeding. I knew what I was getting into. It's too late now! I'm going camping and using my F-150 to do it! HA!
