I say do it if you want, dad worked for chevy for 10 years. There good trucks no matter what problems people try and stick on them. He's also been in the ford business for about 10 years. i asked him one day, he said in his experiance he'd take either one, there about even trucks just look different.
Id hate to see a nice ford replaced by a chevy, but the 2 for one is a nice deal... a dd and a weekend trail rig.
