Thanks for all the responses!
I've decided that I'm not willing to risk losing all the gear I mentioned. I've been mugged before while travelling so know the risks are definitely out there. I'm going to refurbish an old Macbook instead of bringing my new one, it's quite slow for video editing but I am starting to doubt I'll actually have much time to spend editing along the way...so it should do the job.
The D5000 does shoot video, but not full HD and I have never been happy with the quality. I think I'm going to leave it home with my VG30 and get something a bit better at doing both photo and video. Right now I'm looking at the D7100 instead of the D600, it saves some money and by not jumping to full frame I can continue to use the lenses I have. A bit of a compromise but much more reasonable.
I agree that audio is going to be really important. If I stick to the DSLR route, I think I'm just going to get a Rode mic to mount to the camera. Hopefully this does the trick. I was considering an external recorder with some lav mics if I do any interviews...but again I think this might be excessive.
"The more recording stuff one brings, the more one will use it. That can cause missing experiences, or not fully experiencing them because one is too focused on documenting them."
I have definitely suffered from this before...but finding a balance is just something I will have to do during the trip. Documenting it is very important to me.
Thanks again for all the feedback!
