Beginner Strategy question about dry camping / inverter use

Do you know about the power used by devices connected to an inverter, i.e. a Keurig coffee maker will just about drain a standard sized RV battery with one session.

An inverter is a good thing to have and can be of great use but you need to realize the limits of the battery capacity. Your solar module will help to keep the battery charged, it doesn't mean constant 120V through the RV's outlets, though.
