I would suggest checking your voltage every evening and then again in the morning with a decent voltmeter to get a sense of your power uses. I have a simple boat voltmeter from Walmart with several lights indicating current voltage. reads high of 13.6 (green) down to 11.8 (red) clamped on the positive hydraulic pump post & ground. So far we haven't exhausted our 600ah battery bank overnight. Worst case scenario you can run your generator to add power prior to travel while operating your slide & landing gear systems.
