Im a frequent traveler as well.

I own an apartment in my home town. It's my "home". I didn't see it for 3 years. But I still owned it.

Its where I have stored all my stuff and it's fully furnished. When I'm not there, I get it rented long term.

I've traveled for 6 years fot work. Working playing for housing all that time and my life fits in 2 suitcases and a carry on. It's really fun. When I feel unsettled I remember I do actually own a house I can go back to at anytime.
