Also, figured out the ice maker needs to be off. With a full charge, we can turn off generator at 11:00PM, run my CPAP all night and watch satellite TV for an hour or so. Easily make it through the night - generally can get 10 hours with all the stuff running as mentioned. With just the Whirlpool refrig on, I've gotten up to 14 hours.
The keys for us were solid batteries, with all good cells and fully charged. Installed a Pro-Fill battery water system to keep batteries topped of easily and routinely. With 10 weeks dry camping gotta make sure you got the juice for quiet time.

Good info, Thanks! I found & ordered a pro-fill system for mine also. Two of the four batteries will be impossible to access for fill-ups.
