I am traveling across Europe with a self-built camper since 2 years. It might a bit different from what you asked, but maybe it still helps.

Better to choose sturdy things than nice things.

I have a Thinkpad, a mid-range smartphone and a Kindle filled with books.

I use one large military backpack, otherwise only small bags that are adapted to devices (drone, laptop bag, etc.).

The clothes are divided into three categories, nice clothes (suit), normal clothes, and things that have a purely practical use (rain jacket, hiking boots, Poncho etc.).

Make copies of your documents and keep them somewhere different from the originals.

You can prepare well by trying to live like a digital nomad at home. Minimize your belongings, try to live out of your bag.
