Carry oil in your vehicle if it is working that hard you will use some oil even if it never did before. Expect mileage to drop at some points nearly in half. And go 65 at most and you will do fine. You have if I read your post right 550 miles roughly of hauling and 550 miles of cruising. If your vehicle has high miles I might be hesitant but if isn't go for. Just take it easy. I pull a 3500 pound sailboat with a similar sized vehicle a couple of times a year not quite that distant but still a haul and it does fine. Also remember when slowing down I recomend on top of electic brakes to downshift it will save the brakes.
Regardless have fun and enjoy the new truck.
