    Mine's too big for a single axle too, but that's how they did it back in '48. I have a 7500 lb axle on this one. My 2003 Yukon XL 2500 with the 8.1 and 4.10 gears gets about 8-9 mpg towing. Not much better without the trailer, but that's what I got it for anyway. It sure pulls nice! IMG_6355.JPG

    My '02 5.3 gets about the same towing as it does around town - 12ish. Pulling a 2900# car on an aluminum open trailer.

    From what I’ve seen with 3 gas Tahoe’s and one diesel F350 7.3 the gas will see 7-9 mpg and diesel 9-12 mpg towing anything decently sized.

    Just realized our 08 yukon denali xl 6.2 6 spd is going to get 7-9 mpg towing our 4k lb travel trailer. thats about 55 cents per mile! we are definitley at a crossroads decision with RV'ing. Our trip was 164 miles and the fuel was $104 dollars at $4.59 per gallon I am a ca native but straight up FU ca gas prices!

    If I could find one not rotted out in PA I would trade my 09 Denali in and get one just to pull my trailer and find a weekend car.

    2012 Denali XL 6.2 Just did a 300 mile trip up the CA coast with 6500# TT and averaged 8-9MPG , towed great, much better than my previous 2005 XL with the 5.3 - that was similar MPG but it worked really hard, esp. on any grades.

    Can you get E30 over there? Should be less than 87 and will be as good as 92-93.

    we also like the towing capabilities of the 6.2xl. Our TT is maybe 4500 lbs loaded, It really isnt the weight of our trailer, I think it is just the reality of pulling a square box into a headwind? we live in ridgecrest and normally travel north on hwy 395 so we climb "constantly" all the way to mammoth lakes. I should try hwy 101/pch for a beach trip as there would be fewer hill's at sea level and maybe i could see better results in mpg.
