I pull pretty close to 14,000 lbs in my Chevy Avalanche 2500 with 8.1 Vortec and 4:10 rear end. No trouble pulling uphill and fast as hell without the damn boat.

A personal observation:

When towing with a gas engine and a overall 50 ft length of trailer ......

It's a pain in the A$$ to get into a gas station. Even truck stops can be a pain with 72 Feet of overall length.

Flying J is one of the only stops that have a GAS/DIESEL RV lane.

I still like my 8.1L ..... can run with any diesel through cumberland pass or the notorious Knoxville to Ashville I40 route.

Again ... not that it's better ..... it's personal preference....who knows ..next truck may be the Duramax. Either way, the GM is the most comfortable truck I have ever owned. It is equal in comfort to my Navigator that was traded

2,3,4 are correct
I've got a PSD 4x4....at 188,000 miles it has averaged 17.8 mpg non towing.... right at 14.8 mpg towing my 28 Skater.

Most of my gasoline powered friends.....enjoy about 2/3rds of those numbers..... v-10's get half.

35 inch tires have thrown your odometer off.....
You have traveled more miles than it says !!
This explains your crappy fuel consumption.....

i bought an obdII computer to check it out wondering if a sensor or something was bad, jacking up my fuel mileage, but it checked out fine. i can get it down to high 6's with my foot in it towing.
