pump and roll capabilities work best for field fires and huge wet down areas and are limited by the amount of water they carry. we had a 87 mack with a 1800 gal oval tank with a 750gpm american midship mounted tanker with pump and roll capabilities from a seperate pto. pump discharge was depended on the speed of the truck because the pump and truck was controlled by the same throttle. | | |
