Just a caution with 7.3 tranny, some of them are known for blowing a seal when backing up. I dont know the specifics, but a friend has a 350 with a 7.3 PowerStroke which they now call "The Joke" as it blew a seal twice. The Ford mech they are friends with said that tranny is known for it, and you have to put in 4wd but keep the front hubs unlocked or some other witchcraft BS. I wish my 250 had the pulling power of the diesels but I'll stick with my 5.4 after seeing my friend's issues.
Nice truck though, I am a bit jealous
