How long will 2x20 lb propane tanks last?
Assume it is fall and you need to heat the unit and run the generator to charge the batteries. About how long does this much propane last you?

Our Lance 1181 has 2 7 gallon tanks and they hold more than 20#! Propane weighs a shade over 4# per gallon which is why a 7 gallon tank is referred to as a 30# tank 7X4.125= 28.87#. I realize that's not the question, but the capacity and useful duration are going to be quite different between a 5 or 7 gallon. But make sure you know which size tank you actually have. The biggest draw is going to be from a propane generator, which is why we avoid using ours if we are going to be needing a lot of AC, then we take along the Yamaha(gasoline but more efficient).
