I have stopped by the Roscommon equipment build shop where they transform the military trucks into brush fire trucks. It was a very nice, interesting and informative tour. There are only a few employees but they have a can-do attitude when it comes to getting things done. I found it amazing what they get done in their shop. It reminded me of my barn, (in that between the height restrictions and the room left on the side of the truck to work on it when its in the middle of the work area), It leaves allot to be desired. Yet they fit all those different size trucks in to revamp into brush trucks.
Back to my original scoop, they gave me a source for many of their supplies on these trucks, so that if you want to repair or replace any of the stuff.
