Thanks Gavan. It's 7.3 idi. Hourmeter under the hood reads 378 hrs. I saw banks does a turbo kit, but for $3k(!) Looked hard for rust and found none. Didn't see a build plate but it looked very similar to carcrafter22's E350 box as far as layout of doors, lockers, latches, etc. The paint is bright and shiny, even the roof is sharp. It doesn't come with any manuals though and I'm totally at a loss looking in the electronics locker. Everything is perfect and clean in there; do you guys keep it all for camper conversions? Or strip it out and build it back in as needed with commercial RV bits? There's a corporation yard that fixes fire/rescue equipment that I pass on my way to work - I bet somebody'd consult with me for an hour's wage some Saturday. Any websites I can use to read up and get educated on equipment? Thanks again - this is super helpful.
