Interesting read and makes for some good banter, but I don't put much stock into JD Power ratings...
Bottom line is that the big 3 all make GREAT trucks. I have 2 close friends that work at KY Truck building Super Dutys. I have a lot of exposure to Ford trucks...and well my dad, he's a GM guy, only Chevy trucks for his business. When I took my wife's Volt in for oil change a week ago, I looked at a GMC Duramax that was optioned out, beautiful truck! They're all super nice!
Try one or all and pick the one you want, it's your money and if you take care of it it'll treat you right.
