I have called Chevrolet and got the same answer, I can pull any trailer as long as the combined vehicles do not exceed 15000 pounds.
That is not true. There are other ratings you need to consider too. And with an RV, you are likely to exceed something other than the 15k GCWR first.
The 1441 payload is bothering me a bit. Do I subtract 145 pounds from this figure for fuel? I know the tongue weight of about 600 to 700 will have to be deducted.
Payload per the Tire and Loading sticker is with full fluids. Tongue weight, people in the cab, and cargo in the bed all account for payload.
Other than power, there isn't a lot more gained with the 6.2. 5.3 is 9700 pounds tw and the 6.2 is 10,600. GVWRs are 6800 and 7100.
35% more power is not reason enough? :) GM also offers the NHT package which increases payload by about 300 pounds. The 6.2L includes upgraded rear axle/brakes.
The 5.3L will probably be enough. The 6.2L would be better.
