It was a 2005 Ford F-350 ext cab dually with a 7.3 liter Powerstroke. I pulled horses, cattle and flatbed trailers. I got rid of of my livestock then started a town job and drove on average 130+ miles a day round trip to work. I retired the old gal when diesel broke $2.00 ( I thought that was high ) and got a town truck :) Glad I did.
Best of the best!
Especially the 7.3 diesel. No better engine has ever been made; that's why they got rid of it: to sell more new ones.
