Rock River Wyoming has a 1998 pete with 3500 galloons of water and four preconnect hoses. It has power and can act as a tender or throw water, both came in handy on the arapahoe fire this summer. makes good sense as we do not take our pumper/engine out of town andit along with our quick attack and 6x6 can handle whatever is thrown at us in the county
1st out 1000n gal , second out 780 gals , tenders 3000 gal and 1850 gals
Our hill is basically one, climbs from 7000 ft msl to 9000 ft msl or down to 4000 ft msl.
All apparatus are commercial chassis but spec'd with low axle ratios, and maximum torque. In 1 case an add on low speed turbo. These usually mean top end speed is only about 60 but hill climbing is pretty good.
Don't forget retarder brakes, going up fast is good, going down fast --- -not so much
