we fignaly have a chance of getting a new n.f.p.a. approved fire truck and i have a few questions about specs for it. the tank is going to be 3,000 gal and the pump is going to be 750 or 1,000 g.p.m. to classify as a pumper/tanker. i dont like the chassis the diferent mfg.s offer as they only offer freightliner, international, peterbuilt,or kenworth. no macks what so ever. i have contacted several builders but none offer mack. my concerns are which of these is the better truck, and which engines are most reliable cummins or detroit. and what allison trans do you recomend they offer 4 or 6 speeds. i would like to get a manual trans but n.f.p.a. does not recomend them (or so i am told by m.f.g.) they also recomend a engine with at least 350 H.P. but i was thinking more along the lines of 400 to 450 because of the hills and curvy roads that we have here. if all goes well this one truck will take the place of 3 non compliant trucks. (2 tankers and 1 pumper) and we will gain 500 gallons of water in the process. the truck will only be a 2 door cab and as short as possible and still be compliant as it will be a tandem axle truck because of the tank capicity. any and all info will greatly be appreciated. thanks for reading and giving input on this truck...joe
