dry camping with no generator

This too is my plan of attack for this year. We usually camp on electric sites but several times each season find ourselves without power either because park power has failed for one reason or another or the only sites available are dry. In any situation we've run into so far our single G27 Interstate battery has kept us going for a weekend with moderate use but to cover the eventual need to recharge I invested in a Honda EU2000i. In actual practice I found I used the genset so infrequently that I recently decided to sell it and invest some of the proceeds in a pair of new G31 batteries with reserve capacity that matches a pair of 6 volt GC-2s and will therefore not only significantly lengthen the time we can keep going without shore power but will also more effectively power the 1000 watt inverter I installed last year. Since the G27 still holds a charge I'll take it along in the back of the truck as a spare ... JMO, but this is a much simpler approach for those of us who dry camp only occasionally and if push comes to shove I'll always have the G27 in reserve to keep the fridge running or power the awning and slide motors. :)
