I am looking at purchasing a 3500 HD DMAX witht the 3.73 Rear end. I will be towing a 16,000# Gooseneck on the highway 35,000 miles per year. Can anyone tell me what kind of mileage they are getting and what I might expect to get.

Thanks

Depends how hard you hit the gas. If your crusin around 60 flat terrain maybe 13-21 mpg.

pulling my 14,000# (loaded, not gross) gooseneck horse trailer, through the northwest (boise, seattle, portland) I see about 9 mpg avg. I usually run 68-78 mph. Staying average closer to 65 will give me +1 mpg. That is after 15K miles towing for the year.

Just a thougth but if you plan to do 35,000 miles a year why not go to a C4500 the tradein is better they are made to last for longer. I have a 2003 4500 it replaced a 94 GMC 6.5 with 167,000 miles on was told tradein $3,000.00 sold it out of the driveway for $6,800 in New York the dealers have to warrenty used trucks for 3000 miles or 90 days .My 4500 gets approx 14 mpg with only 15,000 miles on it.Hope to get 350,000 miles from this truck,trying to get my moneys worth.Also #16000 you will not know its there.

I pull the trailer in my sig. and usually see around 10 to 11 running hard with a good load. If I'm careful I can get 14 to 15 unloaded, but that's running pretty easy.

I pull a 40' 5ver at 23500-25500 GCW. 8-9mpg's at 65-70mph. I thought about a 4500 but opted for 3500 for easier everyday driving/parking. Same engine/tranny in both I believe. I like the stability of the dually also. Good luck. JJ :)

My 4500 is 6inches shorter than a crewcab and turns within the crewcabs radi 3500's frount wheels are the same as the inboard rear wheels,4500's are set to the out board wheels allowing a shorter turn radi.I have owned both and now like being able to see over the top of most pick-ups and being able to spot trailers in places were I only dreamed about before.

Coastal, I can't think of many trucks that aren't shorter than the crew cabs. I have enough trouble fitting my extended cab in parking spaces, much less the additional 10" of the crewcab. ):h

While the technical aspects of the 4500 sound great, I couldn't get Mama JJ behind the wheel, even for a test drive. :eek: The 4500 is more truck than she wanted to use for daily commuting/driving. Personally I'd jump behind the wheel in a heartbeat. It is a nice truck, especially for hauling.

Critter81, you certainly can't go wrong with either for what you are towing. Happy Holidays! JJ :)

At 16,000 pounds I would be tempted to go to the 2500. Better fuel mileage,(10-14 verses 5-10), 750 pounds lighter, easier to park, cheaper insurance, 2 less tires to replace, No bed sides ripped off when one of your tire blows,etc.
We deliver trailers for a living and currently own three 3500. We are switching back to 2500's as soon as we sell them. In commercial applications some states are cheaper on permits for the 2500. As an example, Arizona charges us $100 for a 30 day permit for each truck just to drive through their fine state. With a 2500 it's free. This is hauling the same exact load. I have pulled 30,000 pounds gross with both, and although the 3500 is more stable, I can't justify the extra expense anymore. And the 2500 in a 4x4 gets around a ton better. Just my .04 cents worth.

Pulling the trailer in my sig. in the North West avg. 9.7. Trailer is 14k+ empty.
