    Maybe if your drag racing, but when you're towing, torque is what maintains your speed when climbing hills or driving into a strong headwind.

    Well the long weekend is upon us and the test begins - towing my travel trailer on a round trip of about 700 kms - here's where I'll be comparing the Sierra's 5.3 L V8 and 6sp with 3.42 gear ratio with my old Nissan Titan's 5.6 L V8 and 5sp

    Heavy duty trailer package doesn't offer a lot. It is RPO code Z82

    The heavy duty cooling package is what you need, RPO code K5L. I think K5L includes KC4 which is engine oil cooler; but I could be wrong.

    Actually, even with the above, 7500 dry is a lot of weight.

    I have a 2000 5.3 , 3.73 gears with towing package and pulled my 6,000 plus pound trailer all day long from Spokane , WA to West Yellowstone which is very high altitude terrain in the summer with no problems. Temp stayed at normal range and averaged 11-13 mpg. Would love to have the 6.2 or diesel but truck is paid off so I'm ok with that. With my cold air intake and magna flow exhaust and Mobil 1 synthetic oil it's a great combination and the engine stays cooler with that oil I believe. Truck on!
