I was told to never ever use the toilet unless absolutely necessary, like an emergency. thank you for the great advice here!
I'm worried about both the toilet seal and dump valve seal, so will put some water in and test it out. Can toilet seals be rejuvinated with vegetable oil, or do they have to be replaced? What about dump valve seals?
How long will a 15 gallon tank go on normal usage for two people? My longer trip planned for later this month will be 3 nights with water and sewer, 3 nights electric only, and three nights again with water and sewer.
