Fresh Water Tank Capacity

Hi,
Can anyone tell me what the fresh water capacity is on a National RV Model M-6350?

Thanks in advance.

  • Thank you all for your help. I was able to find the info by going to Fred's link. FYI: This fresh water tank is 90 gallons.

  • The FRESH water capacity CANNOT exceed the COMBINED capacities of the grey and black tanks. If you know the capacities of two, you can figure out the other....Dennis
  • Or measure LxWxH in inches and divide by 231 to get gallons.
  • Easy to measure it. Time how long it takes to fill a one gallon jug then use the hose to fill your FW tank and do the math.
