Dan, I've had great luck dehydrating bison burger. It has quite a bit less fat in it than "low-fat" beef burger. It rehydrates pretty quickly, and it tastes just like beef. I store the portions in my freezer, vacuum sealed.
As Bob mentioned, you can also buy #10 tins of FD beef, burger, and chicken (as well as other stuff--peas, corn, green beans, FD rice etc.) from a place like theepicenter.com. I wait for a low humidity winter day, open the big can, divide it into individual portions (1.0 oz. for the meat, less for veggies), and vacuum seal them. They remain shelf stable in my cool basement for over a year.
I like to buy 4 pints of my favorite Mexican green chili, and dehydrate it, run it through the food processor, and vacuum seal individual portions. It rehydrates well. Then there are all those items you can buy at Packit Gourmet, like cheeses, yogurt or coconut powder, FD olives, etc. This allows you to stockpile various ingredients for making all sorts of tasty meals.
Generally, anything FD or dehydrated will remain shelf stable for 6-12 months if vacuum sealed and stored in a cool, dry, and dark place. But any meat that you dehydrate yourself must be stored in the fridge (short term--6-12 weeks?), or in the freezer (6-12 months?), preferably vacuum sealed. The fat content is the weak link here.
Combining your own ingredients allows you to create exactly what you want. I like the fact that I can control the salt and fat content, and can I use whatever spices I like. Now, the only time I eat a MH Pro Pack is when I'm in Griz country, and I don't want to create lingering aromas by simmering the good stuff. But there's nothing I like better out there than my spicy Indian chicken masala, red beans & rice with dehydrated spicy chicken sausage (sliced quite thin), good low-fat versions of beef stroganoff and chicken alfredo, or the perfect Mexican concoction. By the way, my meals usually are somewhat fuel-intensive, since I like them best when I can simmer them for 10 minutes or so. I most always have a campfire, which conserves my canister fuel. But you can also create scads of FBC meals, using the ingredients of your choice. Sarbar, Laurie, and Dicentra are the authorities here.
You'll be a busy man this winter, should you choose to get into this dehydrating thing. But you'll never eat drab food on your trips again. I know that most of what I've written comes too late for your upcoming trip, but it should give you some fuel for thought for using your idle time this winter.
