Keep in m mind that the furnace blower only runs intermittently. Not continuously.
Excellent point that seems to be "lost" on many that complain about their propane furnace sucking up so much battery current. I suspect that they may have a weak, or too small, RV battery bank problem instead.
Our furnace runs maybe for 8-10 minutes every 15 minutes, or so, during nights with outside temps in the 30's. That means ~7 amps (furnace draw) for 8-10 minutes every 15 minutes, or so. This translates into around 32 amp hours, total, per 8 hour furnace run per night. Running the furnace all night plus a lot of the day too - is a whole different situation.
32 amp hours should not deplete "a good battery per night". However, we have our furnace control set at only around 62-64 degrees during the night.
