I randomly bought a fire truck a few months ago.
I was looking for something to convert into a camper van, and found my truck:
(A) low mileage, compared to other trucks because of the usage. Ambulances etc. are super high mileage.
(B) they have excellent maintenance, so it’s ship shape
(C) low comparable purchase cost due to tiny resale market.
I’m loving it. Kids love it. Community loves it. Wife tolerates it. Converted it into a camper and party truck!
