ATCme The truck itself is 11 feet wide across the rear tires.. God only know's what she is with the tank on the back. Buy the truck, Leave the tank and when you get her home, Just make a new adapt-a-tank. They were just a big tank with baffles in them and not a big dollar piece of equipment, That is till there is a fire and you have 3000-4000gals of water right away. Then they become priceless. All we use is a Wajax or Honda fire pump on top of them. When we had a fire they were the most valuable piece of equipment anywhere. We would at times have two short fire hose's running off the pump and two guy's on top of the tanker while we drove down the road hosing down the road side's. Worked very well.
