Instead of microwaves stove and an oven I'd be thinking griddle and grills. Of course, for Q, ripping all that out and hoisting in an FEC would do the job as well, both as a certified cooker for a 'kitchen' and as a warmer.
Make sure you know a good mechanic and have them look at it. I'm starting to get the itch on a food truck and those that run them that I've talked to have all echo'd that.
