2003 GMC Sierra 2500HD,4WD, heated seats,diesel, ext cab, well maintained

My truck is a 2003 GMC Sierra 2500HD. It has a diesel engine. I love my truck for many reasons. I love its red color, the fact that it is diesel and gets good fuel mileage. I love its large size but I don't like that often it is hard to park. I love the heated seats in the winter time and the fact that it is 4WD.

My truck has an extended bed, so with the slip tank I don't lose too much space.

So far my GMC runs very well, I am now only needing to put new batteries in her, and a fuel pressure regulator. But I have driven that truck all over, from Colorado to north Dakota and haven't ever had any major problems with it. I would like to purchase a new Duramax, with an Allison transmission in it next.

It reminds me of a tank because it is so sturdy.

I really like this vehicle. It is reliable and sturdy. It is really nice to have around for hauling things. The air does not work so that kind of sucks. And it is really expensive with gas. But other than that I really enjoy this truck and it is good to have around.
