"Im a commercial transporter delievering new and used: 5th wheels, goosnecks and bumper pull RVs, Horsetrailers, cargo, Car and flatbed trailers and boats as well. I average 3500 miles per week, and in just a little over 11 weeks owning it it has 35000 miles already.
Overall rate of 4 stars. No performance, reliabilty or mechaincal issues other than a heated mirror doesnt work-got that warrentied. However, the plasticy leather look interior on my LTZ is both a dust collector and takes some work to keep dust free. Also the interior leg room and repositioning area for me is cramped at best-however im 6'5" tall and large framed. Features are convient and not overstated, Leatherseats are durable and attractive however could use a little more seat suppot-maybe a memeory foam would be better. My truck is loaded with extras that intially i didnt want-that being said the NAVIGAtion system is awesome!!! also the climate control is nice however it always wants to switch to fresh air which is a minor annoyance.
THis truck pulls like a dream, I can pull a 19,000 lb 5th wheel over the mountains out west at 70 mph, and the "grade brake does an adaquite job however i would prefer a Jocabs or other compression brake. THe Allison is smooth loaded, but empty is a harder feel when is changes gears.
Fuel ecomomy ranges from 10-13 loaded 15 to 20 empty. Sweetspot tends to be around 64 MPH empty around 19.0 mpg. Bumper pulls have had the worst fuel economy for me-5th and GNs do much better.
If your looking for all around best performace-this is your beast!!! it has its gliches like the no offered compression brake, lack of luxury finish on the dash cover and door covers, and cramped front seat cabins for the big boys, but they are far outweighed by the pros of this durmax allision powerhouse.
Note: I tested dodge and Fords of same like and kind-Dodge has a Comp brake and great motor as well and now is rumored to have allison as well-however their cabin is just as cramped if not more so and their fuel economy is the same. also not nearly the powerhouse-ive out pulled two 07 dodge cummins up mountains and they had 3000lb smaller trailers!! Ford has a good truck too, but they contune to be plagues by small issue-especailly electrcal and their power is sucky since they did away with the 7.3L. But Ford has some nice interior features that CHev and Dodge dont have. W
Chevy will have the the crowned jewel if they combine a mega-cab with more driver cabin space, and change the plasticy dash and door panels!
Note: to my knowledge-dodge doesnt have a mega-cab with a 8 or 9' box-a requirement of the transporter industry. so be aware of this that 6' box will not corner a traditional 5th wheel without the hydralic slider 5th wheel not allowed in the commercail industry. Another issue which kept e away from Dodge was the small cab on the crew cab dodge-why bother with it you could get a 4 door extended cab with the same room. Ford-great looks and decent room, but power and electrical problems are crazy!!! if you want a ford-go older and get 7.3-then you have a machine and get the 450 or 550. but even they have electrical problems. older chevys 05 and older have injector problems over 170,000 miles which costs 5100$ to fix.
now remeber im coming to you from an industry that puts on 150,000 miles a year and runs these duallys to 6 to 700,000 miles before retiring them!!!! Comfort and relaibilty means more to us then lokks-but chevy seems to have done a 4-5 star job in all areas-especailly the power-WOW!!!!!
"We have 4 of these duramax, allison trans trucks.We have had no problem with any of these trucks. 3 of the 4 trucks never have returned to the shop for anything except routine maintenance. The power is amazing. The diesel engine really shines for farm work where there is a lot of idling. The fuel milage is easily double that of the gas engine under these conditions.
I will be hard to talk out of buying a duramax for my next truck."
"Excellent truck, great for towing. The Allison transmission alone sets this truck above Ford and Dodge. Very comfortable, pretty good mileage considering (I avg 15.6 mpg when not towing), too bad they raised the price of diesel way above gasolline."
"Great truck, use to pull a 38' fifth wheel coach that weighs 15,000lbs. Averaging 13 mpg while pulling at 60 mph and average 18 to 20 mph without coach on highway travel. Very comfortable and powerful. I recommend in a heart beat."
"I purchased this truck to tow our 36ft 5th wheel with three slides, washer/dryer, three friges, three flat screen TVs, and more stuff then you can believe your wife can pack in it. This is got to be my 10th truck I've owned along with travel trailers, and Motor Homes. We work out of town and use our travel trailers and motor homes as second homes. This is the first truck I've owned that can tow a trailer this size like its not there and at amazing speeds. The only problem I've had thus far is the fuel gage sending unit, and the warranty cover that. The crew cab has lots of room and we have the 8ft bed, lots more room."
"Well built, comfortable truck with strong towing capability. I tow a 42' fifth wheel and this truck handles it with ease. Impressive power and fuel mileage averaging 16-17 mpg highway when not towing. Excellent for a 4WD crew cab dually. Lots of useful options such as bluetooth. Best truck that I have owned by far. Have had Ford super duties and before that Chevy's."
"this truck is the best truck i have ever owned. It has great power, it always starts at 9600 foot altitude, even when its cold after snow. It is the best diesel to date and quiet. the transmission is great but could shift down quicker, the trailering button is great. this vehicle is super quiet and super comfortab and rides like a cadillac even though it is a one ton truck. pulls trailers, including my 40 foot fifth wheel like it is not even there."
Pros: "Duramax Diesel Power, great trasmission, hd frame"
Cons: "No 4wd indicator in dash, not enough cubbies"

"And I have owned a lot of em. This truck is powerful, quiet, reliable and hauls our 3500 pound slide in camper with a quad trailer on back with no issue. It returns about 19 mpg highway with the diesel engine and gives 13 loaded down. It tracks and handles excellent. The diesel exhaust brake, new heavy duty frame and bigger brakes and larger heavy springs make this truck truly HD yet still have a decent ride. I have 12000 miles on the truck and have had to return to the dealer only to have a defective mirror heater replaced. At first I thought the urea system would be a pain, but actually it is no more trouble than dealing with window washer fluid. Power is OUTSTANDING and the Allison shifts smooth as glass. Comfort is great with excellent seats, visibility, climate control and audio system. A HD truck like this is not for everyone, but it works great for our needs. I love it."
"I like the truck overall and it has way more power than ford and the alison trans. the feature were that you can shift it yourself is very good for trailering. Also the tow haul mode holds back very well. Over well the truck is great!"
"This truck is a pleasure to drive and will haul all day long. We purchased this for towing our Fifth Wheel RV. It does this with no hesitation.
It is a comfortable ride.
The diesel engine is very quiet compared to some and very little odor when running."
"This is the second diesel chevy i have owned i traded a 03 for this 07 classic.
To date it has proved to be the worst truck deal i have made. It was easy to get 18 to 21 mpg in the 03 and the 07 is lucky to get 14. don't get me wrong the 07 out preforms the 02. But when you add up the loss of fuel econmy and the rising cost of diesel it is about to run me into the poor house. The problems i have had have been minor."
"I tow though the mountains in Colorado all the time and this truck is great towing up the hills and even better going down them. I can set the cruise at 65mph and it will stay between 60 and 70mph going up and down the mountains on I70. This truck is one of the most comfortable vehicles I've ever had."
Pros: "fun to drive, powerful, comfortable, every option"

"I use this vehicle for every day driving and for pulling a 5th wheel. It delivers all the power needed, even through the Rocky Mountains. The ride is comfortable. Has been very dependable.
My only negative is that I have been driving for 50 years and this is the only vehicle that I ever replaced a wheel bearing, it appears the bearings are not sized properly."
Pros: "Fuel, comfort, ability to tow!, OnStar, Sirius."
Cons: "Reading speedometer in bright daylight."

"Great for pulling trailers. No Machanical issues except that I had to replace the batteries at 4 years and I'm on my second set of tires. Very comfortable to drive, no diesel soot to wash off trailer after a cross country drive and its quite compaired to other diesels...no more birds at traffic lights."
"This is my 3rd dually, first one a 2005 Dodge with the 5.9L. Great engine, poor drivetrain. 2nd a 2008 Chevy 6.6L.This truck would pull a coal train but got poor mileage. Traded it for a 2011 Chevy 2500 with the 6.0L Loved the lower payments but the constant downshifting drove me crazy when towing. Just bought the new 2012 Chevy LTZ with the 6.6L After breaking it in hooked a 30' trailer with 17 round bales weighing about a thousand pounds a piece to it. Hay and trailer weight around 23,000 pounds. The Duramax pulled this load 150 miles at 65 MPH. The exhaust brake helped alot slowing the load down. This truck could have pulled another 10,000 pounds with no problem. The 2012 in my opinion is the best produced in resent years. I love this truck!"
Pros: "No frills work truck. Very quiet smooth diesel."
Cons: "Wish it had more towing capacity."

"Compared with the Fords and Rams, the Chevy 3500 HD dually is plain vanilla. Doesn't have the styling of either one of those, but I use this strictly as a hauling and towing vehicle. No King Ranch or Big Horn fur-fru appointments.
Where this truck really outshines the others is in the Isuzu-made diesel engine. It's smooth, very quiet and powerful. I routinely haul 20k plus trailer loads and whlie Im pushing the limits of what it can handle - and it feels like it - this truck chugs along as it should.
The Fords and Rams have rattle box diesels by comparison. If you like that sound, get one of those.
This is my second 3500HD diesel from Chevy and Ive had zero mechanical or electrical problems. But the paint is peeling in a couple of places....not real bad but annoying and the dealer acted like he was doing me a favor by fixing it - within the warrantee period.
Sometimes I look at the new 1 ton trucks by Ford and Ram because they have much higher towing capacity than my 2011, but they run almost 70k ! Ouch.
Unless I come into some $ or this truck starts crapping out, its a keeper."
"I pull heavy loads with this truck weekly (dump trailer and 25' gooseneck flat bed). The truck has been extremely reliable and is comfortable to drive. Great off road and on road. Great truck for contractors."
Cons: "Built in trailer brake controller inadequate"

"I traded in a 2006 3500 HD w/ diesel for this one because of the added towing capacity and exhaust brake feature. I use this truck for towing a triple axle deck-over flatbed with lumber. Total weight runs 20-22k #.
Since I'm pushing the max towing limit with this truck it definitely labors but holds it own. I also plow snow in the winter with it. It does that effortlessly. The miles I have on it are low but hard ones.
The engine is quiet and super clean running. The usual rattle that comes from the Fords and the Dodges simply isn't there with this engine but the diesel purr is there if you listen closely.
The interior is the same as a well equipped Suburban. Same platform. Same seats, etc.
One major gaffe is that they give you a built in brake controller but it doesn't support electric over hydrualic brakes. Hey Chevy...when you are towing over 20k#, what kind of brakes do you think those trailers have?? DUH!!"
"I have owned several Chevy 3500 Crew Cabs over the years. The trucks have been very reliable and pull my trailers very well. This is the first of them that is a diesel and I like it very much. It performs as well as our gas engines did without being loud and obnoxious and, with the Allison Tranny, it rocks pulling trailers through the mountains. I gave it four stars for comfort only because they changed the seats in this model and they are not as comfortable for me as the older styled seats. I am a smaller person and they resized everything for a larger person, it seems. I gave it four stars for quality only because they added more plastic parts. The truck otherwise deserves 5 stars. My '01 had steel bumpers, now you get some sort of plastic that looks beefy. You will not be disappointed with this truck."
