2005 Ford F-350 Super Duty 4dr Crew Cab XL Rwd SB (5.4L 8cyl 6M)
Great fuel mileage at 55mph, about 22, lower as speed increases. People notice the truck. Fun to drive and safe in almost all conditions although it's hard to weigh down the bed in snow because of the large payload capacity. Tows almost anything; I have to look to see if my boat is still attached. Had Dodges and liked them but really like this Ford.
The comfort in this truck is beyond belief. Easily carrys 6 passengers and a full load in the bed without strain. It is fun to drive also. Actually handles very nicely. Wife hates it going through the bank drive-up.
The only improvements are the options I did not select.
