    i think 1500 gallons is a bit to much water for a grass fire. i'd rather see them get like a 1000 gallon(which is still on the high side for a grass truck) and get all the guys wildfire gear.

    perhaps in the east things are different, however 1500 gallons seems excessive for a brush response where perhaps the primary goal should be to cut line. Save your money and invest in wildland gear and training.

    I'll have to back Maplewood up here. A number of years back we were building a brush truck, we contacted the SC Forestry Commssion about how big a tank we could put on the chassis we recieved from them. Their advice was to count each gallon of water at 11 lbs to take in account the added weight of the tank. So, 8.3 lbs per gallon is correct...but since noone has come up with a way to keep water in a liquid state inside a fire truck without a tank, 11 lbs per gallon is a good rule of thumb.

    Hey gah74, heavy water does put out more fire. But its not the stuff we put in our trucks. It is usually red and sticky, moving about 150 mph and dropped about 200 ft off the deck.

    Now, if I use light water, do I have to use twice as much for half the fire load?

    O.k. people go to this pageclark truck equipment and see that a 5 ton millitary truck has a gvw of 70,000lbs. that is heavier than a International Paystar 5000 6x6 that we have that has 4000 gallons of water plus equipment and people and pump that is no where near over loaded. I know because we got the ticket from the certified scales to prove it is correct. As far as go off road, this truck will go any place you can go in a 4x4 pick-up just like the 2.5 ton that we have with 2000 gallons of water, and it does not have any more break down than the other trucks.

    Once again Hope the info helps

    8.34 pounds, does the water tank weigh anything. Yeah he was right 11 pounds per gallon is right on.

    Does heavy water put out more fire than ordinary weight water?

    i did listen and if you know what a gallon of water weighs which is 11 lbs. you take 11 lbs time 1500 which will give you 16,500 lbs (that's without equiptment and pump)there's no way in hell a 5 ton truck can handle that. Sure you could do it for about a year but something gonna give. when you SEVERELY overload a truck like that it's gonna blow or break something. I'd rather see a truck built to heavy than too light.
    It's to big of a risk to ride in if you ask me.
    might work for some guys but there's a reason it says 5 TON TRUCK.

    Hey woody----eleven pounds per gallon?????? God gave you two ears and only one mouth, so try listening twice as much as you spout off.
    Ok-back to the question--there are proably 50 military rigs within a two hour drive of your area. Get off the net and go look, go down to Greenbriar and ask some questions.
    But my question is, with a $3500.oo budget, why take on another expense? It should take your full budget to properly take care of your men and equipment.

    We have a over loaded top heavy 2.5 ton it has 2000 gallons. We got bad info they said it would hold 3000. Now here is what I now know 2.5 ton has a GVW of 23000 the 5 ton has a gvw of 70000. The 2.5 ton we have even being over loaded will go places that the 4x4 pick-up will not. The truck that you have mentioned will work you could even put a 3000 gallon tank on that if you had too.

    Hope the info helps

    This might sound crazy but i think this work for a small underfunded dept like them.
    Put a decent pump(like 500 gpm on it) and then build a tanker trailer to pull behind it(now i don't know you guy's station size if it will fit. But that way it will take some weight off the truck. best of all when you have small fires you don't have to hitch up the trailer. Just the there's a couple things bad about trailers(they can be tricky on snow and ice(if you guys have that),if the other guys are not used to backing trailers they could get anger cause the trailer going the opposite way of the rig. Plus with this idea if you like a field fire or machinery fire(like tractor or combine your probably not gonna need 1500 gallons of water) so if you put like 750 on that leave the 750 or 1000 gallon trailer at the station you'd have enough water. If you go to most Fabrication shops (atleast around here) and tell them how many gallon tank you need and how much the axles gotta weigh and stuff like they they'll make it for you.They usually cut you a discount if it's for F.D. use. we're personally lucky in our dept to have a guy that works as Fabricator. He made our gear rack,foldable chair racks, and i think he's working on folding table racks now. It's just a idea think about it.

    what is the pump and tank size and details of your pumper, also the 2 1/2 ton ?
    I know the area you are in is very hilly and treacherous so i would have to say for a brush truck, you would want to stay with something lighter and more agile. The tanker is needed for structural responses and could also work on brush fires but from a solid road. if the tank on the 2 1/2 ton isnt huge it could be a very effective brush truck, with less chance of getting stuck or rolled over .
    If nothing else build the tanker, house it in the station, and either put the 2 1/2 ton brush truck outside ,empty, or put it in someones shop or barn that is heated.
    we use our old main truck as a brush truck.
    it is a 1974 ford f-700 with a homemade 1000 gal tank and a 70 gpm pto pump, it is the only truck we usually take off road and then only if it is very solid ground. we have two 1 inch redline reels with 200 feet of line on each one, if we need more reach we uncouple the other redline and make a single 400 foot line. we have stuck this truck before but we have always been able to pump the rest of the water off of it and then drive it out under its own power.
    we have also used our 1965 ford pumper a few times as a brush truck, it has a 500 pump and a 500 tank so it isnt as heavy and works good except in the most muddy of conditions.
    As far as Helping Our Own, you know that we are basically shut down right now for lack of funds. I thought i had your dept a great pumper but a small dept in North Carolina responded first and is going to get it. I hope i can get one of the possible return trucks to your dept soon or find you another one to replace your old pumper.
    Most of the equipment and gear we have waiting on us is pretty much all structural stuff. I hope we can get enough depts here needing gear to get together enough funds to cover the shipping costs so we can get a big load or two to Arkansas soon.
    It is a shame that all that gear is just sitting up there in the northeast part of the country and we havent got enough funds to go get it all. there is an estimated 3 to 4 million dollars worth of gear that has been donated.
    Also, are you guys planning on putting some sort of a pump on the 5 ton ? if so which type, portable, pto ???
    Thanks ,Tyler

    Our military brush tanker has a 98,500 pound GVW and weighs 40,000 loaded. It carries 2500 gallons, will climb a 67& slope, go 30 mpg over 18 inch concrete walls, through almost anything as speed.

    i'd have to agree with 443 that's not enough truck for the size of tank you guys want. if water weighs at 11 lbs per gallon times 1500 gallons my calculations come out to 16500 lbs(that's without,pump(which sounds like your gonna put one on),equiptment and men on the truck. when the truck only rated for 10000 lbs it's kinda of a safety issue. I speak from experience of a overloaded brush truck.Our Chevy 3/4 ton 4x4 brush truck has 300 gallon tank and a good size pump on in it and some equiptment on it. we had to put oversize mudder tires on it so it wouldn't squat so much(plus it does better in field fires). Now if you can find a(if they make them) 10 ton 6x6 that would work i think for 1500 gallon tank with pump.good luck with the new truck
