From the Dealer using my truck to tow the owners horse trailer and adding 100 miles to it...to the more than $3000 I had to put into the electrical within 3 months-to the instrument panel stopping to work (speedo, then oil pressure, then battery-which comes and goes) $900 fix it so I just use a GPS for my speedo-to the rattle in the steering because of design issue always going out....to the electric seat positioning clicking 7-8 times before settling into place-to now the heater/AC blower stopped working and a cost of $750 to fix it at PEP Boys.
Thanks to youtube the heater fix will only cost me $150 in parts.
(my friend just had the same thing happen to his Tahoe and had to pay $750.

I've had this truck for almost 4 years, and I have nothing but good to say. I have a 37' 5th wheel, which when loaded is right at 16300 lbs and it pulls it great. Now I'm not going to tell you that I don't know the 5th wheel is back there, but this truck is a joy to drive while pulling. She'll be paid for in a couple of months, and I plan to keep her for a long time.

I purchased the Sierra dually Duramax (LLY - 310hp & 605flbs) to pull a heavy fifth wheel and so far my experience has been trouble free. So far I am fully satisfied although I only have 30,000 km and time will provide more information on reliability of the Duramax. I find it fun to drive and fuel efficiency is good compared to the other diesel (Ford & Chrysler). It provide plenty of performance compare to a gas engine. The interior is perhaps blend as per the critics but it provides a price advantage compare to the Ford's King Ranch. It does not take away from the performance.

I haul a 11'6" Lance Legend camper and
pull a 8'x12' trailer with it loaded
with ATV's and a motorcycle and the
truck does all I want it to. I traded
a Powerstroke in and I am pleased that
I did. It's quite and rides and
handles a lot better then my old Ford.
I am getting around 12mpg at freeway
speeds with this load.

This was the worst vehicle i ever had.
It broke down right as i was pulling
out of the dealership. The dealership
then actually charged me for towing it
the 10 feet to the service area!!
Turns out the axle was faulty. They
also found that the radiator leaked too.

You can always ask for more, but this
truck gives the best of all I have ever
driven. The Duramax is quiet and it
seems to have more pep than my old 350
gas. Over the road unloaded I have
gotten 22 mpg at I-95 speeds. Pulling a
medium size 5th wheel is a pleasure.
The allison transmission is absolutely
super. I will buy another. By the way
my other car is a Ford ambulance
(diesel), the powerstroke is great but
can't hold a candle to the duramax. The
Dodge is just too loud.
