The fact that you went from 1/2 to F with 4.3 gallons would lead me to believe you have a 40 pound tank, not a 76 pound. The numbers on the tank are key to the mystery.

One of 3 things are going on: 1) the RV builder put the wrong tank in...not unheard of, or 2) the float in the tank was not installed correctly, or 3) the tank gauge is faulty. I would take the gauge off and see if there is crud behind it. It is either a snap on or there are two small screws holding it on. It will come off without losing any gas from the tank.
Seeing the 17.6 gal under the tanks all but confirms that that is the pre *0% number; so I am concluding my actual capacity really is 14 gallons (80% of 17.6 GAL number I saw on tank). I can confirm that last Dec I added 10.1 gallons and it was NOT empty.

1. I will confirm tank Monday but I doubt they put in wrong tank? If it were suppose to be larger it would NOT fit. All documentation I have and online say tank capacity is (18 gal) but tank has 17.6 gal number on it.
2. Float may be an issue, I will have them check before it goes off warranty.
3. Tank gauge faulty? If it were out of warranty, I probably would check myself, it has two screws. Kind of odd because the gauge almost block your view of the gauge if that make sense I will have this added to check out with #2 above.

EDIT: the piece blocking the gauge I reference in #3 may actually be the sensor that goes to the inside RV panel on the wall? If so, the way it is installed it covers up about 1/3 of the gauge that is on the tank.
