Do a test-drive at home. Take a one-month period or whatever timeframe you have before taking off and keep all dishes/pots, etc. on the counter that you've used in that one month's time. That will give you a feel of how YOU cook and use your kitchen.
Corelle is highly recommended. Keep in mind that you just might have visitors at some time so plan for perhaps 4 people. A 2 qt. casserole dish would work for potlucks if you're invited to one. It can also be used to cook a roast or chicken, etc. We loved our convection oven and it will cook anything just like a regular oven so experiment with it. I'd take a 9x13 and 8" square baking pan for desserts, brownies. A cookie sheet, too - even for a treat of a warm fresh chocolate chip cookie made from a refrigerated dept. Pillsbury cookie dough. You'd impress a guest! Extra silverware doesn't take up much room otherwise you'll find yourself always washing dishes and using that precious water if you dry camp. If you have the room a hand mixer, toaster, coffee pot and crockpot would be the only appliances you'd really need.
Again, you'll just have to tailor it according to YOUR needs and how YOU cook. Everyone is different.
