I'm always amazed at how much I can store in my microwave while traveling. Bags of chips, loaf's of bread, smores ingredients etc. I'd keep the microwave then you have one if you need one, plus resale value should be considered. Many people like the conveniences of home while camping.
If you plan on staying in places with electrical hook ups I would agree with the generator delete. If you plan on boondocking in hot climates either keep it or order an AC you can use with a portable generator as suggested above.
