Does anyone have experience moving far away with very few bags?
No.
I have lived and worked abroad - in different countries and continents - for long periods of my life, - often in trying, challenging and testing environments - but I take the view that it is a good idea to bring some of what I need with me. That means at least one large suitcase, and, on occasion, two, if I am to be away for longer than two months.
If you don't bring it with you, you may have to buy replacements instead. This might not be a good idea when money is tight, - as I believe may be the situation with you - or you are working in the sort of underdeveloped spot where such things might not be readily available for purchase.
