Just had the same experience on a 4000 km trip to PEI and back with a 5100 lb. trailer.

Wind and hills were brutal on the 2009 Suburban. No problem on 'regular' roads at 100 k/h and no issue with transports passing. And guess what, I never passed another vehicle in 2 weeks while towing ...

I have the 5.3 L, 6 speed, with 3.43 rear end. Even with a 3.73 or 4.1 rear there is not enough guts in the 5.3 L for big hills or fighting 40 mph headwinds towing 5K. Kept Tow-Haul on most of the time to limit shifting and ran at 2500-3500 rpm and watched the gas gauge as the tank quickly went down. I got 10-14 mpg (UK gallons) at each fill up. My TV computer indicated 50 litres /100 km current fuel efficiency on some hills. I added a transmission oil cooler before the trip. My highest trans temp was 200 F at a 90 F daytime temp towing.

Looking for a Sierra 2500 Duramax Allison ...

Been in exactly the same boat as you have. We pulled a Jayco 27BH that was about 5k lbs with a half ton suburban. Living in Montana we have the grades to climb and descend and needed more power. After a year of over taxing our tow rig, we traded it in on a 2009 3/4 ton suburban with the 6.0 L gas engine. What a difference! Worth every penny when going up and down those big grades. The transmission with the tow-haul and +/- buttons was great as well. The suburban came with an integrated trailer brake and the Big extending mirrors and was a towing machine. The only reason we sold it was to get a diesel truck so we could pull a 5th wheel.

Sorry for the confusion. I am in Ottawa Canada and we used the British system until some politicians introduced metric here. So my mileage numbers are referenced in "miles per UK gallon". A US gallon is about 20% less.

Gas here is sold in litres, current prices in Eastern Canada are $1.30 to $1.45 per litre, and 1 US gallon is 3.8 litres, so $4.94 to $5.51 per US gallon for gas here.
