doug, I certainly hope no one takes your advice. You are all over the place,
and giving advice your simply don't know is contradictory. Please be quiet.
If you fail that simple thing, I ask anyone who hears your advice to triple
check it with someone who has actually been there.

3,000 amps in battery capacity, dougies. geesh.

That is the way battery ratings work.)

I know. Such a small battery is not suitable for any forced air heating
system.

doug, a brand new, fully-charged Grp 27 battery will give up about 50 to
60
amps before it is dead.

I suspect you mean amp-hours since amps is not a measure of capacity.

Even more when going to flat dead. That Espar ran
that brand new, fully-charged Grp 27 battery flat dead in about 6 hours.
Flat
dead.

50-60AH at the 20 hour rate which is normally how batteries are rated. A 5
or 6
amp draw is much higher than the 20 hr rate. More like a 10 hr rate or
worse.

of course, it was not 68* outside. More like low 40's.

Depends upon what temperature the thermostat is set at, the outside temp,
how well the boats is insulated, etc. Sorry, a Group 27 battery just isn't
suited
for a forced air system. Isn;t really suited for much of a refrigeration
system
either.
