Fresh water tank

I have 25' safari with a fresh water tank. I have honestly never used it...



We always have water hookup...



My trailer is a 1998 and I would be very curious to see the inside of that tank...



I had a 1977 trillium trailer that I removed the fresh water tank and that tank was disgusting... Full of mold...



Also, why people are traveling with fresh water tank full?? Your afraid of running out of water?? To use the toilet?? When traveling I keep a gallons of water to flush the toilet... Not 400 pounds of water...
