Sorry I didn't get back to you sooner. Out here on Cedar Key, FL and basically took a vacation from the internet and cell phones for a few days (ahhhhhhhh....).
I run a Norcold AC/DC fridge (8 amp draw - the smaller model), house lights (some incandescent and some LED ) an AM/FM/CD stereo and occassional VHF. I can last out like that for at least 3 days. Don't run any mwave or other heavy-draw appliances. I have a small inverter for a fan in the cockpit area and charging/running the laptop. I also have a Honda 2000EI generator that can charge the whole shooting match up, as well as an 80 amp alternator on the single engine. THe Fridge is the biggest amp-sucker and it cycles 3-4 times an hour for maybe a total of 20 minutes each hour. Knowing the total probable draw on your system will give you a very good idea of the amount of time you'll have without having to charge up.
I think you;d be able to run most of your stuff on the two 29s you bought if they were dedicated to the house bank.
I also have a Blue Seas ACR (auto charging relay) that automatically keeps track of my batteries and never lets the engine bank get drawn down. I also regulates the state of charge on both banks when underway using the alternator or at the dock when plugged in to shore power. I never ever have to mess around with the battery switch since the ACR does all the switching automatically.
