Stupid questions.... Help

I have the Shamrock 21dk Hybrid. Can I run the furnace with the propane if my hot water heater has been drained for winter?
Second stupid question:
How long will my battery run the furnace before going dead if that is the only thing pulling on it?

Yes you can just make sure the switch for the water heater is off. The furnace blower will drain your battery probably fairly quickly depending on amp draw of blower motor, battery condition etc.

Battery probably won't make it the night if it's cold out but depends of course how often it comes on.

Yes 1st question, 2nd question you can always parallel a good second battery to the existing good battery and or fire a genny up to replenish your batteries.

If I plug the TT back into the TV and run the motor for a 1/2 hr will that recharge the battery?

It would take hours if not all day and then some.

Our 1st trailer was a small 16'. We could go 1 and 1/2 nites on One
12 v battery. This was when temps were near 32 at night and the furnace
was not used during the day. We'd set the thermostat to 50 or 55
at night and the furnace ran several times each night. Unfortunately the
furnace blower is a power hog. So are lights so you want to use LED
bulbs in your lights or portable flashlights for interior lights at night.

Also note I'm talking about nearly fully discharging the battery in that
time. Fully discharging a battery shortens it's life significantly.

Also note a dead battery won't be able to keep your fridge control board
alive and so you won't have LP refrigerator after the battery is dead.

Many campgrounds around us have electric. Even some national forest
CGs have electric so winter camping is possible for us.

Also-- get flannel sheets!! And use a down comforter or down sleeping
bag opened up as a comforter on the bed!!

Finally- a small generator- even a 1KW genny can re-charge your
trailer battery. It will likely take 2 or 3 hours per day to keep charged
if you are using your furnace every night.

Good luck and Welcome to FRF!!
PS- there are no stupid questions here! We were all newbies at one time.

Happy Trails!
