I'm in same boat. I am doing a 10 battery deep cycle bank, with two optima batteries isolated solely for starting..but havent done the #'s to see how much power i need for my AC since my bus doesnt have it stock I need it pretty mucy 24/7 so thought maybe a small 2500 generator like those little hondas mounted under bus in ventilated box ran to batteries to keep them charged when runningAC and hopefully the converter/inverter i get will have an auto on/off so i dont have to manually turn on gen everytime I want to start the AC. Also thought just for now since I am also building custom rear bumper that over hangs (not that big though but now you got me thinking) but am also pulling a small trailor for my bathroom, storage tools shower etc.. but putting a 3500-5k gen in the trailor. only thing, when i dont have trailor connected i wont have my generator

Keep the post goin guys and pics ofwhere you all have yours jerry rigged!!!
