I have been thinking about a flat black paint job but the original paint is in such nice shape I can't bring myself to cover it up. All the emergency lights have been disabled, blue lights have been removed. I've never been hassled or been given any grief about the paint colors. Kept the side and rear flood lights working.
Does have the 7.3l diesel non turbo with an auto, wish it was a 5 speed. Cruises down the road at 68 mph at 2000prm, gets 14-15 mpg, unless I'm in the mountains. All aluminum body, all 1/4 inch plate, very well built. Will put bigger tires on once these wear out. Has 215 75 16 now, putting 235 75 16 tires on should get me a little higher cruising speed. Runs awesome and drives down the road like a new truck.
I purchased this rig about 7-8 years ago and couldn't be happier with it. Couple new batteries and some wiring repair and its been the most trouble free, reliable rig I own. So I would suggest if your thinking about going this route don't wait. They don't come up for sale very often so do your homework and be ready to go once you find one.
Buying the ambulance got me looking at other service cars which lead to buying a squad car.
