I tried to fill my fresh water tank time so that I could sanitize it. According to the owner's manual, it has a 75 gallon tank but using a flow meter to measure the amount of water, was only able to put in about 50 gallons before it started coming out of the overflow. I checked the freshwater guage and it registered 2/3rds full. I am the third owner and the unit has had very little use. Last year I tried to fill the tank and discovered that the tank connections were crossed up and as the tank filled, the weight of the water pulled the connectors out of the tank wall. I replaced the plastic connectors with brass fittings. During last season, I only carried about 10 gallons of water for roadside potty stops. Any ideas why it only seems to hold 50 gallons? When I worked on it last year, the tank filled the available space so it seems like the correct tank.
Thanks!
