My town has one of these-- "Utility #1" they call it.
It gets sent out after snowstorms with a strong willing on-call firefighter (kid making $12/hr) to shovel out hydrants.
Only road it sees is slushy and salty.
No, wait, they probably plow through underbrush with it as well. Maybe they jump in and floor it without warming it up, too.
Yeah it does get washed, but they floated a bond for a new one because the frame rusted out on the old one.
