That is a good dehydrator :-) You will have fun! And if you don't have any, go get a box of parchment paper from the grocery store. You can cut circles to fit the trays-and it reusable. Btw, I have been doing more dehydrating info on my website, under the Gear section. Lots of pictorials on how to dry stuff!
And best of all? If you dehydrate full meals (lets say you have leftovers at dinner time) those meals can be done in a freezer bag on the trail!
