Other than the diesel, that is the same truck we bought in 2000 for our first commercially made TC. The camper package held our 2600 lb. camper great. If you have air bags, even better for keeping the back end up when inflated to 60-80 pounds. I will bet the lance 915 is about 2600-2700 empty, which should be fine. We never carried the water tank full because of the extra weight. We also sometimes towed a boat and trailer, which needed a 18" extension into the receiver. That weighed about 1300 lb, with about 80 pounds on the trailer ball. Again, that was fine. We have done the same with all 3 of our F250's and have weighed in at 10000 pounds loaded up for trips.
