    cant buy a truck and call it a truck unless you got a v8. if you pulling a load and using a small v8 your gonna get worse gas milleage than a truck that has a bigger engine cause it dosent have to work as hard. it might end up being close to the same but still a truck should have a v8. 2500 or f250+ should be diesel deff not gas.

    That really depends on your use. Only you can decide. I have a chevy 1500 half ton,paid for and wouldn't dream of getting anything smaller for better gas milage why. Here's why. On day's I don't need the trailer,( tandem axle 18 ft used to pull zturn,push mowers, and capable of hauling my JD tractor 4,000lbs and other stuff it will get 18-19 miles mpg when pulling big trailer it drops to 10-11 miles mpg. On the days that I can get by using my smaller 14ft tandem it still drops mpg to 12-14 mpg. If you have to your equipment to do the work then you have to have a trailer. A single axle trailer bounces your equipment all over, up and down and beats it to pieces. And if you have a blow out, look out. A smaller truck won't do the job. It will either struggle with the engine trying to pull the load, thereby using just as much gas and putting a strain on the engine and maybe tearing it up sooner or tearing up a transmission. Most people that by a truck for good mpg's are people that just go to work to the office every day but not real work, and get a high speed rear end to match the transmission to get the best gas milage. However if you want a truck that is going to do pulling and you want the transmission to stand up to the jerks and strains of everyday wear and tear, then get a real work truck, but only you can be the one to know what you needs are.

    One variable that is usually overlooked is the axle ratios:
    One of my old trucks is a 93 F150 regular cab, long bed, 2 wheel drive, no a.c., 300-6 & 5 speed manual with 2.73 rear axle ratio. In town it got 13.5 mpg. Highway it got nearly 20mpg. With good tune and alignment low 20s on the highway. Most of my driving is in town. With some research I found out the same truck with a 3.55 rear axle ratio would get 15-18 mpg in town & about 18 mpg on the highway. Those years F150s could be bought with 2.73 (2wd only) , 3.08, 3.55 axle ratios. In 94 they started offering a 3.31 axle ratio.
    A friend of mine has owned many 1/2 ton Chevy/GMC trucks with the 4.3 V6 and 3.42 axle ratios. He would get about 17-19mpg everywhere he goes. His newest GMC 1/2 ton 4x4 shortbed with 4.3 V6 truck only came with a 3.73 axle ratio and he gets 14mpg everywhere he goes.

    It's just like with all the folks who would like me to work for free :p
    I can't do it, I'll do it as low as I can go above the bare costs, but free ain't happening.

    The problem is that at least with used trucks which are capable of pulling the weight and also get good fuel economy,
    they are in such high demand that the price difference is more than noticeable, the cheapest trucks always have the
    biggest engines, with used trucks nobody wants the gas guzzler.

    It's so bad, when I bought my truck 4 years ago for $2500...
    An equivalent truck that got decent fuel economy would have cost me $4000!
    No, I am not kidding, you want a truck that's even remotely priced around Blue Book, then you're getting a guzzler.
    Amazing how vehicles can be priced 40-100% over the price of Blue Book, but that's apparently the way it is.

    We're talking my truck gets 10mpg, one that would have gotten 14+ would've cost me.
    Well I can tell you for that $1500 I can buy a lot of extra fuel, it takes me 3-4 years in the price difference to even notice.

    The only other truck you can find that gets good fuel mileage and does not cost an arm and a leg
    is usually a bit slow on the uptake, like perhaps certain used government vehicles, or as someone
    else mentioned, some V6 / 5.0 (305 / 318) V8.

    Which is why I am always either driving a gas guzzler, or a truck that's a slouch.

    Because you won't find powerful economy cheap.
