Yes and no. Most reference information is kept at the station or dispatch center. The information that we keep in the truck are in binders and is limited to hazmat and a street directory with hydrant locations and some preplans for the few commercial structures we have in town. Our rescue truck does carry more detailed info including all of the new information from the website that I mentioned. Some of the larger departments in the US may use a similar system to yours but my department is small, 7 peices of apparatus. Check it out at www.mallettsbayfire.com
