thanks for the replies guys. Talon seems better to me too for sure especially with the low weight and gear range, but of course I can't get Old Man Mountain specific racks here so I probably can't carry panniers on the front which makes it hard. So it seems there are a number of approaches to handle my issue, but I'm just a bit limited because of my location in Nepal.

I was thinking that either:

A) I order a B.O.B trailer - but will cost ALOT - import taxes are super high.
B) I try to get a similar trailer custom made here but assuming that will be very challenging.
C) A different trailer like this one: https://goo.gl/RUhJsT - cons of this are the constant bounce over the ****ty terrain, and the extra response if i take on flight.

And

D) Try a mix of bike packing and panniers. Bike packing ONLY i think is not possible because this is a long term trip (with all camping/cooking gear, plus electronics to do documentary filming) but maybe if I have 2 back panniers, plus a smaller bag under the middle frame and a handlebar bag - and try to even the weight out as much as possible, it could work?

What do you think?
