Microwave use is not an important requirement compared to all the other things I would like to be able to run, so optionally I can just plan to cook with propane instead in trips without shore power.
I think that makes a whole lot of sense. Propane is much much more energy dense than lead-acid batteries, though of course cannot be "recharged" using solar power.
A crock pot often works nicely with solar power. Just take care to investigate the power requirement; a normal traditional crock pot uses a pretty low wattage element, maybe a couple hundred watts, but there are also dual-use ones that can be fryers and have a much larger element. You would want the first kind, of course.
