formulas for energy audit?
Getting ready to a long trip next summer with a few nights boon docking and thinking generator, battery bank, inverters etc and know I need to do an energy audit for my trailer. Trying to put togethe...

Thanks for all the advice gang. The goal? Man, there are a few actually. For now, the goal is to figure out how long I "could" last on just my gp24 house "deep cycle/Marine" battery. I'm under the impression, it's 70 amp hour... so maybe 35 amp hour if at 50%
We've done three days, no furnace, fridge on gas/12v for control. All LED lighting and a 23" LED TV running off a small inverter into the cig adpt.
We plan on a two week trip next year and figure there will be three days of dry camping on either end for travel and staying at Camp Wallyworld. We'll have a genny for the trip.. so really, this is all moot but at the end of the day how long the house batt lasts will have a baring on how much time the genny needs to be running. Again, I'm sure that monning coffee and microwave use at meal times running on the genny will be more than enough for battery top up till we make it to the GC on day three or four.
I'm also trying to figure out, is it possible to make morning coffee off the inverter with out destroying the house battery? Then the house battery could top up on the drive for the day between Walmarts. So if there is no Microwave needed for breakfast.. and it's just the coffee maker.... will I want to fire up the genny?
I have a killawatt and was playing with it today. So far, what I've seen, running on shore power of course it that with everything on... and I mean, every light, the water pump running, the bathroom fan on, and microwave heating a cup of water, I'm drawing 16/17 amps AC. I"ve done the same, running the AC instead of the Microwave.. and the draw is about the same.
So really with the Energy Audit, I want to figure out, morning coffee, lights, water running for clean up and washing. How many nights I could do this... (based on time used for each device of course)... if I would need to fire up the genny.. or would the tow vehicle be enough to top off the battery?
And of course, I'm a tech geek at heart and know that i'll be switching to a bigger battery and likely solar at some point.. so it's all good stuff to know. :)
