TT has a microwave, and we use it every single trip, with or without shore power. If we're not on shore power, I start the genny, run the microwave, get the meal done, and then shut down the genny. Keeps the batteries topped off too. DW and I don't like to spend much time cooking when we're on the road. So, we normally make casseroles, stews, curries, and chowders ahead of time, put them in Lock and Locks, throw in the freezer, and then warm them up in the microwave, eat on paper, and call it a night. I spend my entire week cooking healthy meals with lots of prep... the last thing I want to do on my precious time on the road is the same thing I do each night. So, nuke the meal, sit outside, smoke a cigar, sip some gin. We like it. I would replace it if it broke.
