Well, from my experience of hauling massive loads to small loads, I can say the biggest thing is You do need a heavy rear spring and a good trailer brake controller. The biggest mistake I ever made was I was in a pinch one time and had to pull a 2 horse bumper pull without a trailer brake controller. I also didn't have heavy rear springs. This was in a 1/2 ton. Now people are gonna think, oh... heavy horses, blah blah blah.... An aluminum trailer and 2 horses is around 4400 lbs. One of the worst feelings I ever had. Now, if you got a double axle trailer, a good trailer brake controller, and set the brakes slightly higher than the vehicles brakes, you should be ok for short flat hauls, but to me the rear end will feel slushy. But hell, with the 8 horse and a 3500 we set the trailer brakes higher than the truck.
