I have a 04 E350 6l PSD cargo, working on seat mounts to install set of set of bucket seats for 2 nd row, and brackets for bench 3 rd row. Pop the bench out, toss in storage/bed box and instant camper. Getin' close to 100k on it, needs to go in for inspection. Drove an 88 E350 7.3 for 4 yrs, did 1 set of uppers and changed 1 set of tires in the 210k I put on it. It had 760k on it when I parked at behind the local High School as a project for them.
