I bought my truck when I was 19. I put 75,000 miles on it. I sold it at 175,000 miles driving her from Phoenix, az. To San Diego, ca. To Austin, tx to Houston, tx. & to Kansas City, mo. I hauled cars on trailers around az. & tx. I also hauled my stuff in the bed from Phoenix to Austin. I drove the hell out of that truck going 100 mph+ from Phoenix to San Diego. Of course I took it off road and raced some cars & trucks on occasion. I did the work on it myself & she had all the power, towing capability, & even drove her while I delivered pizzas at domino's. I could pull 16-18 mpg in town. I can't own another truck now, since she was easy to work on, had enough power and towing, & I could scare little cars too.
Easy to drive. Plenty of power with the 5.9 360 V-8.
Just the gas maybe, but I made it work driving 1000 miles a month, and some of that time gas was at $3.60 a gallon.
