    What do you intend to do with the truck? Do you need a gas guzzling one ton?

    Do you have the 8 grand?

    I'd take the 1 ton but you might not use your 1/2ton as hard as I do. And the 1ton shouldn't get much worse fuel milage then the 1/2ton. I see about 10mpg out of my 98 right now.

    Are you only getting 10 when just driving around, no plow?

    Well, the 98 is twice the work truck. But it's going to use more fuel, and repairs will be more expensive. Very nice platform for a plow truck, probably the best of that generation.

    I can get 12 if I'm easy on it, 10 right now is about normal. Best I've gotten is 17mpg on the hwy. With my plow I see about 7-8mpg.

    Truck is about 6200lbs 3/4 of the year. In the winter it's about 6800lbs w/balast and then around 7500lbs with the plow on up to about 8600lbs if I'm loaded up to go salt. And a lightbar and plow mount not helping the aerodynamics, and 285 tires vs the 245s it was stock with. And 3.73 gears so it has to work a little to get up to speed.

    Mark, that still sounds really low for a 1/2 ton. I get the same with my 2500 which is 6000 lbs empty, and spends most of its time loaded up. It has either 3.73 or 4.10's, not sure.

    And to the OP x2....do you have the 8 grand? Your current truck will work with a plow for a lot less than that, but if you intent to throw a v box spreader on there or do any heavy hauling, or towing more than 6k or so, it might be worth the upgrade.

    My truck would probably get much better if it wasn't so heavy and had 245 tires on it vs the 285s it has right now. My truck has to work a little to get up to 60mph, when the plow is on and I've got a trailer it takes it a while to get up to 60mph but holds it ok once I'm there as long as I keep it in 3rd.

    Your truck should have 4.10s since you have the 4l80e.

    4L80e doesn't automatically mean 4.10 gears. My ECLB SLT has 4.10 gears. My friend has a RCLB SL with 3.73 gears. Both trucks have 350 engines, 4L80e trans.

    We both run stock tires. He can get 16 or better around town. I can squeeze 15 on the highway.

    How many miles oh your truck? Your uncle's truck has new plow and a new motor,deal doesn't sound to shabby. How hard do you plan on working it? I always buy HD's or 3500 trucks. Regular cabs are recommended over extended cabs . Used to be some plow dealers[fisher] didn't want to put plows on extended or crew cabs. Warranty could be voided. plowking

    Have some gussets welded on the UCA brackets. Do a search, there are several threads.
    Install Timbrens.
    Top quality shocks - Bilstein are very popular.
    When you do any front end work, use only top quality parts. Moog, Napa Premium, etc
    Big transmission cooler, transmission temp gauge, service transmission EVERY year
    Synthetic fluids in transmission, transfer case, axles.

    Go easy on it, watch your trans temps.

    And throw a set of air bags in the back if you want to carry a bunch of weight. One of the best upgrades ever done to my truck IMO
