The 4.3 would not be my first choice for a trailer pulling truck.You don't give a weight for the tractor & trailer,but I'm guessing 8000lbs or more for both.For what you want the truck to do,I would look toward a 1 ton,you get a bit heavier truck & bigger brakes as well.You don't want to get into the situation of the tail wagging the dog!
