    Default 1500 5.3 vs 2500 6.0l 2010 towing economy with 1500 kg load

    Hi, i really hesitate which pickup to buy .

    I hesitate between

    2010 1500 4x4 with 5.3l extended cab with 8 feet box
    2010 2500hd 4x4 with 6.0l crew cab with 8 feet box

    the main reason i want a 2500hd is because the 8 feed box and crew cab.

    I will drive about 8000k mile year
    80% of my driving will to go to my cottage with trailer about 1500kg
    I have to run 350 mile through mountain when I go to my cottage.

    which mpg should I get with a 6.0l versus a 5.3l for my use ?
    is the 2500hd crew cab vs the 1500 extended cab will worth the extra money I will spend on fuel ?

    Thank a lot Christ !

    As much as I like my 5.3 powered 2011 CrewCab if I were doing as much towing as you plan I'd go with the 6.0 2500, in the end youll be happier, especially traveling through mountains.
    Mileage differences with a load on the back and running up and down hills will be negligable, less than 6mph difference.

    I'd also throw my vote to the 6.0L 2500. I don't know if the 6.0L has the AFM system or not but if it does not that would be one more reason not to get the 5.3L

    My opinion.........
    2010 Silverado LT 1500 5.3L 4X4
    '95 BMW K1100LT
    '97 BMW K1100LT
