Like the title states, I will be towing 6500+lbs to North Carolina this weekend. The trailer has a single axle brake and I installed a brake controller lastnight. I have factory springs in the rear with 5100 series billies back there also and a spacer lift. I'm gonna be pulling a 1st gen double cab taco up there with bumper and 35's. I am also going to have the truck over the axles and more to the rear of the trailer, to keep from looking at the sky while I drive, but I am going to have ENOUGH weight on the front of the trailer to squat the runner a little bit so I know I will be safe there. The bed of the truck is going to be loaded with a dinner table, sliders, and some miscellaneous stuff. I might try and throw the sliders on the roof of the 4Runner to keep from adding more to the bed. I have a 2005 Limited V8 4x4. I guess I am posting this to get everyone's input.
