It allows more weight to be ran for ballast in the bed for traction to be able to push. My DRW comment wasnt about the weight of the plow, it was more about being able to move it full of snow.
How much ballast do you have that you need a dually for it? A 2500HD SRW has plenty of rear axle capacity for ballast. It's actually the same axle in the 2500HD, 3500HD SRW, and 3500HD DRW. The 3500HD adds a helper leaf, the DRW adds another set of wheels... adding to tire cost and increasing "float". Good for dry traction, what does having twice the rear tire do in snow?

Great for towing a big trailer, an unnecessary cost for plowing. DRW with a diesel gets you 5200 lbs vs 4600 on the SRW gas.
You made the comment, not me. So I figured you were basing it on something????
Math, plow manufacturers and commercial plowing operations.
My money is on the diesel getting better economy. Especially pushing snow and even driving down the road with the big air dam up front. My 5.9 cummins in plow trim weighing in at 11.5k and pushing a 8.5'+wings (10' total) and I get 10-12mpg on the road and 1.5 gal/hr plowing.
My 5.3 chevy with lighter 7.5+wings weighs just 7500 ballasted, barley got 10mpg driving, did about the same pushing (but a smaller amount of snow), and didnt have near the pushing power.
I never recommended a 5.3.
Plug the diesel in. In all seriousness though, in a plow event that can last 10+ hours, there is only 1 "warm-up".
I'm assuming it would be plugged in.
All the parts on the trucks are the same except the engine/trans. A case can be made for the diesel being more durable in a hard use environment like plowing. But in either case, engine/trans parts for either aint gonna be cheap.
The diesel is more durable, but unnecessarily so as plowing isn't that hard on the engine, but just about everything else on the truck. You're right, the rest of the parts are the same price. But realize the Duramax is a hugely expensive add-on to the truck, I think like $8500 IIRC.
Not sure what the weight difference is between an 05 duramax engine/trans and an 05 6.0 engine and trans, but I bet it isnt as much as some think. I think it being "harder" on the truck is a bit far fetched.
Go look at front axle gross weights, and then compare it to what plows manufacturers allow their dealers to install. You can install just about any plow on a 6.0 3/4-ton, you have
far fewer options on a 3500HD DRW.
Most of the guys I plow with, or see plowing, are running diesels. Those that arent are usually just starting out. And FWIW, almost everyone I know that runs a chevy gasser from the late 90's to present has issues overheating on the highway unless they keep there plow LOOOOWWW. low enough they they bounce it off the pavement every bump or expansion joint they cross.
Interesting. That's very different here where most commercial plow operations are running gassers. The ones with diesel duallys are pulling huge trailers with mini hoes and stuff, so the dual-purpose truck saves them money.
I don't know about the older trucks with plows, but between the 6.0 and the Duramax, the Duramax definitely has more overheating problems. Never heard an issue with either plowing, but plenty in 100-110+ heat.
I don't see a lot of commercial plow trucks operating "on the highway" though around here.
Plowing is plowing. IF you like a gas truck...great. IF you want a diesel, thats fine too. But IMO, the arguments you make for a gasser being better are simply unfounded
The topic was "setting up a duramax for plowing", which I assumed to be commercial since he said he was going into the business. Now the topic is "setting up a duramax for plowing 2 driveways" which is a whole different story. I stick by my guns that the 6.0 is a better choice for commercial plowing. Go talk to your plow dealer or a commercial operator.When you are running a business, what you like and what makes you more money are sometimes two different things.
I love the Duramax. I am on my 3rd and I've been driving them since 2004... a 2013 3500HD SRW Denali with 24,000 miles I bought new. I also love diesels - my daily driver is a 2014 Passat TDI. That doesn't mean it is the right choice for everything. A lot of guys go out and buy a $65,000 Denali 3500 and then use that for roof tear-offs and snow plowing, and wonder why they don't have any money. Or they put on a huge lift kit and huge tires and then go plowing. Same guys that run around everywhere with strobe lights and light bars and everything else turned on like they're emergency workers.
If I was to be in the market for a work truck it would definitely be a 2500HD 6.0. Now, the initial post was that he wanted to set up his truck to get into the plowing business. Now it's revealed to be a farm truck that will maybe do 2 driveways. Throw a home made 16' wood plow on it, who cares? Big difference in the two scenarios
