Ok, Guys
here is what I have.
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.
Truck I am looking at has a gross weight rating of 6800. Payload in the truck is 1441 pounds. Taken from truck sticker.
Trailer weight is 5872 from yellow sticker on trailer.around Loaded I will estimate around 7000.
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.
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.
Rear axle is 3950 rear and 3650 front. 7600 total on the 5.3
Will I be overloading this rig with the 5.3 and 3.42.
thanks again
