I inherited an 03 Dakota 2 years ago. I live in the Northeast and not having 4WD pretty much just doesn't work out. It gets stuck every time there is more than 3 inches of snow on the ground, and slides all over the place in any snow or ice (which is pretty much 3 full months a year). Piling weight in the back just doesn't seem to help. The fuel economy is terrible for a 2wd vehicle, my count is about 18 mph highway at best but i have got as little as 8 city. The Truck would be fine in a snow less region, but if you live in a cold climate look elsewhere. You can get much more traction power without sacrificing too much in MPG.
Nice big center console with a power outlet.
Fuel efficiency, RWD provides 0 traction, ext cab couldn't hold a dog let alone a human.
