If you regularly top off both, use the Top Off button.
Rereading this, I've made my reply more confusing than helpful, so I'll try 1 more time. To start, the Fuel Used
function is for planning, not tracking, in order to advise you where to anticipate your next gas stop should occur on your chosen route.
: The total gallons of fuel you can carry in your truck or RV. In your case, 68 gal. (20 gal. tank + 48 gal. aux).
: The # of gallons remaining in your tank(s) that you set as the trigger for RVTW to notify you that you should start looking for your next fuel stop.
1. Fuel Used
: From Stop-to-Stop in your itinerary (whether Gas Stop or Other) RVTW calculates gas consumption in gallons based on miles traveled (within RVTW) divided by the Avg. MPG you establish in the RV Info tab of your Settings. RVTW calculates this fuel consumption for each and every Stop-to-Stop segment.
2. Fuel Remaining
: The total amount of fuel, in gallons, in your tank(s) at your last fuel stop (this is normally your Fuel Capacity
unless you choose to use a lesser number.), less the cumulative fuel used in each travel segment since that last fuel stop.
If you typically leave a gas stop with both your main and aux tanks full, you can just use the Top Off Fuel
button to bring your gas to 68 gallons after your planned fuel stop. RVTW will then start the gas consumption calculation again to show you where the next fuel stop should be anticipated on your route. If you don't leave with both tanks full, then you'll have to do the fuel upload calculation yourself to establish what you typically leave a gas station with in terms of gallons of gas. RVTW will then use that number as the basis for your next notification to look for a gas stop.
Hopefully this is helpful.
