Today we got called to assist our neighboring fire department with a structure fire. So we sent an engine, a tanker and an ambulance. They established a water supply in a very remote location using two portable pumps and were having trouble keeping up with the tankers that were filling at the water supply then hauling the water to scene to dump. So they called for our trailer pump and since I was late showing up I was still at the station. So I brought it. This was after I had drove ten miles back of rain soaked roads but when we were up at the location, the truck/pump were absolutely covered in mud.
The reason it is sagging so much in the back is because there is over 500 ft of soaking wet mud packed 3" hose rolled up in the bed.
