My mother in law has the Colorado...and I got one as a loaner when my Duramax went in for first oil change, which was free.Have you looked at a GMC Canyon yet? I had a 19 Denali crew cab long box with the duramax 2.8, the truck was rated to tow 7,700 pounds, although a bit pokey off the line. This truck has tons of torque, and I could easily get 35mpg on the highway. My wife had a crew cab short box V6 version, the engine drive trail combination rips, I’d say better than my F150 work truck with the 2.7. Go do some test drives, and pick what you like. Cheers
For a family, I'd stick with the full sized trucks. Price isn't that much different, but performance is. Stick with the 1/2 ton's. Extended cabs will work while your kids are young...they will quickly be kicking the back of your seat. : )
Not a fan of rust...and understand why some would shy away from Chevy/GMC. I will tell you in all my years, and owning 8 different GM trucks, I have never had issues with the powertrain. everything from the massively underpowered 305 V8 to the 496/8.1 Big Block (awesome engine!), and now the DMax. Transmissions always solid, engines even better.
I've heard very good things about the Ford turbo v6's...wonder how they will hold up.
