The typical RV motorhome propane tank that has a metal plate stating the capacity is 12.2 gallons will only hold about 9.5 gallons or less. How much it holds depends on where the overfill protection device shuts off the input port. I am guessing your coach has a 20 gallon propane tank and the 80% volume is 16 gallons. Your system has been calibrated to indicate 100 % at 16 gallons. We have installed the SeeLevel system on our coach and have calibrated the LP gauge on the SeeLevel to 100% with the tank full. Time will tell how accurate that will be but we are expecting the tank to accept around 5 gallons when the gauge says 50%.
