ive got a 2001 dodge ram diesel and i like it alot. its an auto, gets pretty decent mileage even tho its chipped, exhaust and intake. it pulls my 20 foot enclosed no problem. ive had it coming up on 2 years now and have yet to have had a problem with it. it also just turned over 100,000 miles. i drove a ford one time and didnt like it. id say just go drive them all. auto and 6 speed and see which you like the best.
