If i were to buy a new truck with a gas engine i would buy a new ford F-250 with the V10, XL, crew cab, short bed, 4x4 with the manual transfer case and standerd transmission ( ford has a problem with the automatic tranny after about 95,000 miles), now if i was looking at a new diesel truck i would get a dodge ram 2500 with the cummims that is one awsome truck. stay away from the ford trucks with the 6.0 liter diesel they had a lot of trouble with them. for 2008 ford came out with a new 6.4 liter twin turbo diesel, it might be a good engine but then again it might not because it's only the first year for the 6.4 so i would wait a year or two for ford to work out all of the bugs before i would buy it.
