Unless I am missing something, it doesn't seem like there are really any high current components to a camper other than possibly the jacks. Perhaps the furnance blower and water pump but even then, thouse items are cylical. For those with battery monitors, how many amp hours do you typically pull in a day? My current batteries on my most recent trip to Tahoe lasted nearly a full week with a 20 watt solar panel and 30 minutes once on the genset.
Even if I got just 2 or 3 days using one of these battery solutions, I'm thinking the tradeoff in volume and weight savings would be well worth it. Couple it with a 200 watt solar panel and I have to think you would be covered power wise. Heck, you only really need the battery to last through the night if you have a large enough solar array to top up during the day.
If we flip the equation from trying to maximize our battery capacity for multi-day stints to minimizing our consumption and optimizing the system to sustain for 24 hours with a full recharge what is really necessary?
