I have to admit that it is not enough truck for that big camper. But, as an owner of a 96 V-10 Gasser, outside of not having enough brakes to slow anything near that size down, the power is there (at least on mine it is). You might as well open your wallet and pour the money out though, they are real hungry for gas when loaded heavy. I have hauled alot of heavy stuff with mine over the last 170,000 miles but this one is pushing the limit even for me. The gasser for me, when I purchased the 96, was the logical choice. The additional $6K for the Cummins and having turned a wrench in a truck shop all of my life, the wife did not want the smell or the noise anywhere around (I did not really either). I have had braking and front end issues with the truck until I repaired it after warranty tried. After 170,000 the radiator leaks some, the trans leaks a tad bit but it will still get with the program (and does regularly still). We just need to pour cash into the fuel tank when we do. No, the V-10 in the trucks does not require Premium fuel (It does, however like mid grade ALOT).
