The tires alone are taller than my daily driver car, and EXPENSIVE! 1700 apiece, from Michellin of Australia... the front axle has a 21,000 GVW rating, and this had a past life as a mixer truck in a Florida mine.
Now it does special jobs, like movie location wetting, construction site watering down for foundation compaction, is (or has) worked some local fires, and soon a couple of accessories will be added to allow for remote controlled water cannon projection of up to 1/4 mile.
