Best handling vehicle for all weather.
My 2004 GMC sierra 2500hd, with a 8 foot bed, has been one of the most reliable vehicles I have ever owned. It handles amazingly in all types of weather. It hauls my 40 ft camper with no problems. My least favorite thing about it is the seats. They are very uncomfortable with no support.

It is the beast!! Jacked up and loud.
It is been a good work truck. The people before me ran it hard and abused it but it still runs strong. I haven't had any major problems. The only thing I hate is there is some rust on it but I am hoping to fix that in the near future. My truck has 228k on it one motor, second transmission but it pulls big equipment.

This car is affordable and practical; a great deal!.
Love the size of the truck. The ability to use it for hauling things. Excellent handling. Hate the amount of gas it uses.

GMC is superior to all other trucks.
No real problems, just regular maintenance. Plenty of power, very reliable, comfy despite the 3/4 ton suspension. The rhino lined bed really adds to the durability. I wish I could've found the 6. 6 diesel model but none were around. Because I have a lift kit and larger tires, the fuel mileage suffers slightly.

Maintenance. It is important to keep up on them.
It is awesome. It is a great truck that does whatever I need it to. I wouldn't trade it for the world no matter what.

It is sturdy and dependable. It gets us where we need to go!
It is dependable, has a double cab, so we have room for extra people. It is sturdy and gets the job done. We have had very few problems with it.

It pulls great. I don't even realize I'm pulling a trailer.
I love my truck. It pulls my horse trailer great. I wish it were 4 wheel drive and had less miles.

The big GMC that can run over or through anything.
It is a good truck that does what it is supposed to. Haven't had any major problems with it just regularly little things that wear out over time. It can haul a lot of weight and gets up and goes when I need it to. It does use a lot of gas though because I have it jacked up with big tires and a chip.

Reliable heavy duty truck.
This truck has been very reliable. I have owned it since brand new. Very strong motor, and heavy duty. Bad things about it are the gas mileage is terrible. Parts are expensive. The ride is very rough also but that is scorecard with a heavy duty truck. Overall it's a great truck.

2004 GMC sierra 2500 extended cab solid, heavy duty work truck.
It is a solid, heavy duty GMC sierra with high mileage (267,000) and still runs strong. It is an extended cab basic work truck with few factory options. The truck is low geared, something I do not care for but am used to. It has had regular wear items replaced (brakes, radiator, alternator etc.) However the motor and drivetrain are original. It is a NH truck so inevitably it is had some rusting. The rockers were replaced. It has taken a lot of abuse towing boats, snowmobile trailers, and also used for plowing and amazing still running.
