 Bought my 2008 F350 DRW 6.4 twin turbo diesel 3 years ago with 67000 miles on it. Purchased to pull a 38', 13000# fifth wheel both on short trips to the lake and longer cross country trips. The truck now has 79000 miles on it with about 90% of them pulling the fiver and the observations are as follows: 1) Fuel economy sucks, with (9 mpg) or without (12 mpg) the trailer. 2) With the Lariat trim package, leather, etc., interior comfort and appointment are like sitting in the family room at home. 3) More than enough power and road stability to pull 13000+# regardless of conditions or locations, has seen the plains, mountains and deserts, on interstate, U.S. and state highways as well as county roads, city streets and dirt country roads across 16 states and just keeps on going like a dream. Have 2 more trips, 10 more states and about 6000 more miles planned this summer and have had no experiences that would lead me to expect anything different. and 4) maintenance and repair costs have been minimal and limited to standards scheduled trips to the dealers quick lube location. Have owned Dodge, Chevy and Ford trucks (mostly Ford) ( currently also own 2009 F150 STX extended cab w/90000 one owner miles), from half-ton to one ton and this one has done nothing but solidify my feelings that Ford is "Built Tough" and will continue to be the truck that graces my driveway.
