Ok I should soon be purchasing a new to me (used vehicle). I have just recently test driven a Chevy 1500, a 2500 Duramax, and a Ford F150. The F150 felt like a dog and in both that I test drove the A/C did not work. All the Chevy's that I test drove the A/C would freeze us out. Not sure if thats a issue but none the less I like driving the Chevy better. I am talking here about 2003 and up Chevy's and 2005 up Ford F150. The drivetrain on the Chevy just felt better. The Ford did feel more rigid and the steering was better. I do not mean this to turn into a Ford vs Chevy war. I am not partial to any brand. I just want the best truck for the money. I am looking to spend around $17 to $19k. I want the truck to do some light duty off road duty and possibly a lot of traveling. (Do to my job). I could be doing some light towing every now and then. So my real question is Should I lean toward the diesel (which I really really want) even though for the money I am looking to spend the vehicle will have around 100k miles on it or should I lean toward the 1/2 tons and get one with less miles? Thanks again for your time and Im sorry it was long but I wanted to put my opinion of what I test drove and to see if that is common? TIA
