Aaron, thanks for the information. I won't let the RV battery go below 50% charge. The inverter will be used primarily to operate small appliances on an as-needed basis, such as a fan and coffee pot, and to keep a residential refrigerator cold by plugging it in intermittently. I will dry camp for only a night or two, and will have a spare, fully charged, RV battery just in case. I learned to swim by being thrown into the deep end of the pool. I guess I'll learn to dry camp the same way. I know a small generator is probably a better way, but I really don't want to mess with gas cans and the noise, whatever the decibel level may be. This is as close to "roughing it" that this old boy can handle.
