Well we finally found the one for us. It's taken a year of thinking and dreaming, then more than six month of hunting, but the hunt is over. I give you Harvey.
It's a 2001 International FE, DT266E, MD3060 (need to verify the trans), 189XXX miles and has already been stripped inside. To boot, it was only a little over a hour from home. There's minimal rust, it is a southern bus, just a bit by the stairs. I assume it's from the tire getting mud up in there. Other than that, it's pretty clean. The price seemed reasonable, our mechanic gave it a clean bill of health, so we pulled the trigger. It runs and drives great and we're super excited!
I'm not totally sure of the exact body type, but it does have Thomas markings in the electrical area, but is badged as an International.
Y'all get ready for a pile of questions. WE GOT A BUS!
