Keurig coffee makers for the RV

Are you planning on using this with an inverter? If so, take a close look at the wattage of the Keurig machines. Many are up around 1500-1800 watts, which requires a pretty hefty inverter and battery bank. (Obviously they don't use that amount of power for extended periods of time, so the total energy consumption is not too extreme, but it's a big surge to deal with.)

If you're going to be running a generator or connected to shore power, that is of course a lot less of a concern.
