I think your OK, since its all flat, just watch out for the winds....I towed my new Voltage V3895 about 75 miles, over mountains 9K, with a Chevy 2500 Short Bed SW and I was right on the limits, My truck was on order, I now have a Chevy 3500HD CC LB DRW with Air Bags. Your truck is still new, but I think you will have to upgrade, since you don't have anything in it. You will add more then a couple Hundred powers?
