I did that the first year, too. And the second year. And it wasn't really "doing the apples" - it was, like, one or a few batches.
I don't plan to dry tomatoes. I have too many other things that are higher priority for drying, even if I get another dehydrator. Tomatoes are so juicy, I want a different kind of tray before I do more than try a few. Besides, they are so easy to can, I'm doing that. I like freezing them first, then the dunk in boiling water is faster, the skins come off much better, and I don't burn my fingers.
