We did a 6000 mile cross country trip this summer with our grandsons. All went well except my odometer quit working (speedo and trip odometer still working) shortly after we started and apparently the propane level indicator is no longer functioning show empty (lights above door show two red no yellow or green). I know this because I tried to fill the tank twice only to put in 5 gallons the first time and nothing the second time, they opened the bleeder valve and leaked mostly fluid out. Obviously the tank was full.

I would like to correct both of these problems and would like advice from anyone who can assist me on this.
