No, but every time you cook something you can toss a serving or two in the dehydrator, or cook double and put one batch in a dehydrator. Spagheti, soups, stews, so much you can dehydrate. 3 Mountain House meals will pay for a cheap dehydrator. What I've read is good for 6 months to a year on a shelf and indefinitely in a freezer. I have a weeks worth still left in the freezer for my camping this year.I can't eat Mountain House for three months.
I did that prepping for an 11 day camping trip. I've eaten plenty of Mountain House on weekend trips. I pulled 3 off the shelf and realized that was a cheap dehydrator so I bought one. The result in the middle of the woods around a campfire is I thought someone brought the whole kitchen and cooked dinner right then. I dried spaghetti with meat sauce and stuffed pepper soup. Both were just made 2 minutes ago in the kitchen quality. You just can't dehydrate milk products. I read that as I had steak, alfredo, and noodles going already. I tried to re-hydrate one and it did NOT work out.
