Ross,
My dept. just retired a type 1 engine, I'm tempted to buy it and have my own! Not really, type ones are too big. We do have a couple of pick-ups with water that will be retired someday. I'll get one of those. We do have a type 3 that may go in the next few years, more tempting than the type 1.
Until then, just a lot of old retired hose and a pump.
