06 E350 extended, seats pulled for a cargo van. Purchased at 26,000 now 207,000. Synthetic oil every 5-6,000 miles, tranny fluid every 50,000, anti-freeze at 50K and 150K. Plugs at 100K and i COP. Was taking it in for plugs, COPS and tranny fluid when the tranny went. Like the van enough that I'm putting in a 5 year 75K mile warranty for $2,700 with synthetic fluid.
Sure hope that doen't bite me in the butt. Uses about a quart of oil every 5,000.
3001 F250 4x4, 214,000 6.8L. Runs like new.
