    Scaled the D-max today

    Curious what it weighed compared to my old 79 1 ton.

    Orion, you had mentioned your Dmax doesn't stop very well, as well as a friends Dmax. I mentioned I'm experiencing the same thing. Might have something to do with the weight of the truck.

    This is a 2500HD crew cab short bed 4x4.

    With a full 26 gallons of fuel, no driver/passenger, 33" tires, and an aftermarket exhaust (that certainly lightened it up), and it still scaled 6,845 lbs.

    So with one decent sized person it's already over the 7,000 lbs. mark. It definately has some girth. Hard to imagine with all the plastic stuff they put on these cars nowadays.

    For comparison sake, my 79 1 ton with a big block/auto, long bed 2 wheel drive and 1/2 tank of fuel (20 gallons) scaled at 5,230 lbs without a driver.

    That shouldn't surprise me, but it does a little bit. But I guess it makes sense. The dealership I work at used to sell Hummers. And we couldn't lift the H2s on our old 7000 pound hoists if they had a couple accessories like aftermarket wheels and bulky brush guards. Which means, those short wheel-based, "3/4" ton chassis/axle, 6.0 gas V8s, H2s with factory 35s were weighing close to 6500 to 6800 pounds stock.
    And the tree-huggers were pissed off. Mean while all the trucks running around were weighing the same and getting the same crappy gas-mileage.
    I hate people.

    Not surprised at the suburban, they aren't small vehicles, but that Durango is a bit of a shock at 5,200. Those aren't that large, and I've rented them before when on vacation, they don't drive like a 5,000 lbs. vehicle.

    Considering that's as much as my 79, and it has big heavy stuff in it. Large 10.5" ring gear 14 bolt full floater rear, big block chevy and 400 turbo, dual gas tanks, even the wheels are overkill compared to other trucks of that vintage. Darn steel wheels are so thick I have to modify wheel weights to knock them on the bead when balancing the tires. 16.5" diameter and they weigh 65 lbs. a piece, Not to mention the whole truck is made of steel.

    I already knew mine was in the 7500 lb range. Makes the 20+ mpg even more impressive. I've always blamed the shitty brakes on the whole power steering brake boosted set up. I don't really understand it or know anything about it. I know why they use it but it's the first vehicle I've had like that. The dodge diesel trucks are heavier than ours & stop much better.

    We also had an 05 Durango & you're right.....it doesn't drive like a heavy vehicle & oddly enough ours got pretty decent mileage even with the gas guzzler 4.7 in it. Much better than the trucks. I'm guessing gearing played a big part in that. The dodge truck probably has 3.73 or 4.11 rears & the durango had 3.55's

    I just noticed this. I'm surprised a dealership would even install the little 7,000 lbs. lifts, especially since they sell Hummers.

    Yep I was thinking the same thing, 20 mpg and over 7,000 lbs. is pretty damn impressive.

    I actually like the hyrdo-boost brake system. It's flawless on my old 79 1 ton and stops on a dime. I even added hydro-boost to the chevelle because the engine didn't make enough vacuum and an extra vacuum canister wasn't cutting it.

    I tend to blame the shitty D-max brakes on the smallish disc brakes all around. They could stand to be a lot bigger considering the size and girth of that truck, especially the rear. Disc pads just don't have a large contact surface area. Only way to improve it is larger diameter rotors and larger calipers.

    The Dmax has another version of the GM 14 bolt, full floater axles, with a bolt in pinion (like a 9") with an 11.5" ring gear diameter. Same thing that is in my 79 1 ton but with a 10.5" ring gear.

    The rear has been around a long time.

    After driving my Dad's Dmax truck a couple days back, I'd easily bet on it stopping waaaaaay shorter than any 79. It stops just fine, and the calipers and rotors on that thing are massive IMO. It's a regular cab, long bed 2500 though, so definitely lighter weight than any of the crew cabs, etc. It also has over 50K miles on it, and shows almost no discernible brake wear from new.

    My Dmax seems to stop just as good as my 04 Tahoe, both sporting hydroboost. The Dmax will also run circles around the Tahoe Friend of mine said his 2005 Dodge 2500 with a cummins and a M6 hit 7,200 on the scales.

    They were old, old hoists from the 80s. We replaced them with 12000 pound hoists which are great for lifting BIG trucks, Hummer H1s, and those huge 12 passenger Express/Savana vans.

    Suburban with the 5.3 and DOD will pull almost 18 on the highway. Hook up the trailer and that drops to around 9.3 mpg.

    That makes sense. I have a 12,000 pounder (2 post) in my shop that has picked up anything I've had in there. Getting ready to buy a 10,000 lbs 4 post for other more specific jobs.
