Pre-cooling Dometic in 2014 8528IKWS fifth

With propane on, without shore power, and the single-fully charged--12v battery on in our brand new 8528IKWS, we began pre-cooling our standard Dometic refrigerator at about 2:30pm. By the next morning at 9am, while the refrigerator had cooled during the night, we found the Dometic trying to restart it's gas system, and just clicking. The battery was virtually dead. Is this normal?
BTW, the system all worked fine when connected to our truck and driving 4 hours.
Any suggestions would Really be appreciated!
We are getting ready to leave for 3 weeks soon; and you can be a big help!
We are also suffering a Very loud fan--compared to our previous RV; but that's another issue, from what I see on the forum.

I'm just guessing here but there must have been a few other things drawing from your battery. Just the refrigerator a good battery should last quite a bit longer than that

Well according to my chart..
normal appliance amp draws

At minimum 3.5 amps were being drawn.

Depending on your battery size 3.5 amps could be quite substantial.

Co detector 1 amp
Gas detector .5 amps
Fridge 2 amps

My fridge usually takes a long time to "fire" when it hasn't been in use for a while. I light a burner or two on the stove to make sure the propane is moving and the fridge fires up pretty quick.
