I had a nice Tacoma rated to tow 6500 pounds. I bought a travel trailer that weighed 4700 pounds. The Tacoma had plenty of power, but it got a little squirrely rounding a downhill curve. A little research and a trip to the scales showed me that I had exceeded the 1200 pound payload capacity of the truck.
Part of the blame goes to the RV sales person. They'll quote the trailer weight and the tow rating of your vehicle. Sure, the trailer is in range of the capacity of the truck, but you'll exceed the cargo capacity long before you'll exceed the towing capacity. When you add 6 to 7 hundred pounds of tongue weight, it leaves very little cargo capacity for passengers, bikes, kayaks, and chairs.
Sure, you can add air bags or helper springs, but you haven't increased the legal payload capacity.
I have gathered all do the data to do a detailed article on towing specifically geared to Broncos. I really need to gather the last little bit and get to writing.
