I drive a Ford F250 Power Stroke Diesel 4X4 Lariet --extended cab (not the crewcab) Wish it was! Its a 2001 with 237,000 miles but hauls like there is no tomorrow. I haul a 3h bp, a 30ft fifth wheel RV and an 18' bp flatbed--- never a problem Hubby is a diesel mechanic and swears by this engine so of course that is what we've got---- I love it, great truck with decent fuel mileage. What are your thoughts? What do you drive? Why?
