Hi,I am a volunteer firefighter from central Virginia. We are looking to buy a new brush/attack truck. We are a rural county so we don't have many hydrants. Thus the need to be able to use the truck for water supply.We are currently looking at a 500GPM slide in unit by HALE. We are also looking at a minipumper manufactured by Pierce. It to is also 500GPM but is PTO on a Ford 550. What I would like to know if anyone has any pros or cons on the above pumps, please let me know.Or email me at MBois2@aol.com
