My wife dehydrates jasmine rice in our dehydrator on every trip, either by itself, or mixed with casseroles, burritos, etc..  She typically cooks everything in an Instant Pot to make it easier.  Plus, when you pressure cook chicken, you can easily shred it and dehydrate it and it will come back really well compared to other cooking methods.  Almost every Instant Pot recipe we've tried works well since it's basically all one-pot stuff that tastes good together.

We use a basic 4-tray Excalibur dehydrator that I got from Walmart a few years ago and the food always re-hydrates really well in ~20 mins after boiling.  I'm fairly certain she soaks the rice first to remove most of the starch before cooking, but then we just dehydrate like normal on parchment paper squares on the trays.  Sometimes she separates the beef/chicken from the meal, depending on what we're making but most of the time, it's just all in together.  She does break up any clumps once it starts firming up to make sure it dehydrates evenly.

We either cook in a single pot for canoe camping or re-hydrate with boiling water in a screw top Ziploc container in Reflectix-style cozies for backpacking with equally good results.  Even when bringing to a boil in a single pot, letting it sit for ~15-20 mins sealed in a cozy (or your toque) is the key to allowing the food to fully absorb the water.

I used to weigh before/after to get the water volume exact but have since evolved to just barely covering the food and adding more cold water after re-hydrating if it comes out too dry.  It makes it so much easier and eliminates the need for a measuring cup.  Plus, it is quicker to eat since a touch of cold water cools it down just enough not to scald you.

Another tip we've found is that if you're cooking right in the pot, it's best cold-soak for ~10 mins before you're ready to cook.  It ensures that even the harder to re-hydrate ingredients come back without having to simmer and waste fuel.

The system looks like it works pretty well for the most part, but I guess I won't know for sure until I actually start booking for the first spring trip.

I did notice that it's lacking the ability to check how many sites are available/occupied for each lake like the old system had.  I, along with I'm sure many of you, often use this to determine how "crowded" certain lakes will be and plan our trip accordingly.  I've emailed the developers and they said they will look into exposing that detail so hopefully it gets implemented before next season.
