Camper pitfalls

I own a 2012 Ford F-250 short bed with the 6.7 I have a AF 811 that when loaded is at about 5K and I pull a 7.5K boat and trailer with no problem. My AF sticks off the back of the truck about 32 inches and I am using a supertruss hitch and extension. My boat trailer tongue weight is 750 pounds. Now with that said I have made many upgrades to handle the weight. I have airbags, I have upgraded both front and rear stabilizers, I am using the torklift spring additions, and I have upgraded my wheels and tires. It took a little bit of time to get to find the sweet spot with the air pressure in the bags but now it handles really well. I have put many miles on it over the years with no problems.
