If your serious about a 1/2 ton truck, look at the newly designed 2007-2012 toyota tundra with 5.7L in a DC 381 hp and 401 lbs. of torque - that thing goes and made in San Antonio TX with 80% American made parts more so than any of the other Big 3 1/2 ton trucks. The price is very similar equipped to the chevy silverado crew cab and will hold their resale value better than all the rest of the 1/2 ton trucks on the market for sure.
I have had a new Tundra for a few months... love it... have always had Fords since there was a Ford mechanic in the family. Now retired and in California, so no help. Stick to Toyota!!!! Even Consumer areports rate it good!!!
