I found that the Equalizer load leveling trailer hitches work quite well. I used to pull a 26' race trailer with a 2000 F150 5.4L before I got a F250 diesel. It pulled about as hard unloaded as it did loaded due to the wind drag. It wasn't fun going on the expressway and made it quite stressful just because the weight of the trailer pulled the truck around. A semi passing would about put me in the other lane. For everyday I would go at least a 3/4 ton.
