At work we are in the market for a new truck, for the past 5 years we have been using a 2004 Dodge 1500 with the 6.7L V6, double cab with a short box, we put about 5,000 to 7,000 miles per year on it 90% of the time it's towing a 18 foot trailer, half the time that trailer has 1,000+ pounds of granite and tools on it.
We've averaged around 10mpg and seen as high as 12mpg with the trailer, without it will get up to 16-18mpg.
After about 70,000 miles we are starting to see transmission troubles and I am sure that the engine has been over worked a bit, the body... well I had a little mishap with it yesterday and it made us start talking more about replacing it sooner rather then later.
Anyway, looking for suggestions on a work truck, the double cab is nice as small tools and supplies can be stored inside and locked up, the amount of weight we tow has been hard on it being a half ton truck but most of the issues have been more so in the transmission and brakes, today we borrowed a Chevy 3500 with a diesel and we were not impressed, it felt as gutless as our half ton gasoline truck.
Of course we don't need something that is way over kill, when we get a big shipment in or something we hire it out to a trucking company.
