I've done it. It's not rocket science, but there are some things you can do to make it easier.
Use parchment paper (NOT waxed paper, learned this the hard way) on your trays
Avoid any excess fats/oils
Keep chopped items small in size, i.e. your veggies, meat, etch
I store the meals in Ziploc freezer bags (quart size) and put them in the freezer. They'll keep at least a year. Soups and stews are easy. Some pasta dishes work pretty well, like spaghetti. I've dehydrated chicken breast and mixed it with couscous and seasoning. The chicken will take a while to rehydrate.
The biggest thing you need to adjust to is the length of time it takes to rehydrate. Expect 20-30 minutes for meals once you add your water. If you're okay with this, it's a great system. If you want to eat in 10 minutes, stick with freeze dried.
