Which one did you get dank86?
Can you dehydrate things like a curry? We would love to be able to eat a homemade madras or korma when we are out.
Just as a follow up to this - dehydrating things is easy once you get into a 'routine', but be prepared to spend a few days doing it when it comes to heavy food like curries. It seems ideal for making things like dehydrated banana or fruits in general/features for adding to meals, but dehydrating full proper meals takes 15-30 hours of non-stop dehydrating and some of the dehydrating trays on the cheaper models are, shall we say, not destined to be long lasting.
By far the worst food to dehydrate is anything with a significant amount of fat in it - simple put it goes rather weird during the dehydration process, so if you're cooking curries specifically don't use ghee, use the leanest meat you can get. Vegetarian curries seem to fare a lot better in that respect, you can then bring a bag of cooked meats specifically to add with it which you cooked the day before your trip - for example.
If I was doing the whole dehydration route again I'd either find someone with a 'proper' dehydrator to borrow or buy one with a bit of longevity in mind, and commit to putting a few long distance trips in the diary to make that saving more immediate and substantial. For example the Excalibur Dehydrators are known as one of the best out there for speed/build quality and range from £140-£240 - if I was less inclined to buy one outright then you could get a few mates to pitch in £50-70 each and share it when we want to do a batch of dehydrating it actually becomes quite cheap, dehydrates faster, trays last longer and helps everyone have more access to longer trips outdoors. Especially since you only ever dehydrate things in bulk batches anyway, throw them in zip bags in the freezer. It pays for itself for the first long distance trip you do, effectively.
