I have no way of answering your first question. Basic physics suggests it won't be a rocket ship going up grades.
From the specifications in the manual available from the Cummins/Onan website, the Onan QG3600LP (which I would assume this generator is) uses 1.5 lbs/hr under no load, 2.2 lbs/hr under half load, and 3.3 lbs/hr under full load. Propane generators use a lot of propane; getting a diesel generator, if possible, would definitely be preferable in my opinion as it uses less fuel (diesel fuel is more energy dense), the tank is bigger, and it's easier to find places to fill it up.
