This is an official "PING" - I guess. I'm back from the Caribbean - it's my every-year winter vacation. That's the advantage to living in MN -- March is a great time to leave town for a while, especially if you're heading south.
Like any one who rebuilds ambulances, I watched every ambulance I saw carefully. Unfortunately, the Caribbean island roads are universally sized for horses, wagons, and maybe Model T's, so I didn't see any medium ambulances - just a mixture of standard Ford chassis equipment, and Mercedes-based units.
