You are in Luck.....the one you want is for sale right now on this forum, and it is here in AZ........in Flagstaff
And it is a ford with the 7.3 diesel and has 4wd.....everything you are asking for, for only about $45k.
I am interested in this unit too, but it may still be too early for me to buy since I have to get rid of three other vehicles first!
So I say to you.....go for it, don't delay any further 'cause this is the one you want!
Good luck....find it at
