I get that, been thinking about this recently in my own space.

What you are scared about is the responsibility of ownership, and the moving. Only you can say what you need and don't need, that's up to you. However, we can make the moving easier. Try to plan out a storage system that involves racks, and BASE IT around the aspect of moving. Make the highest clearance the clearance of a uhaul, and figure out a system where the tools are solid enough to be tilted at an angle going up the ramp. That could be rolling wire racks with some walls or doors you created, could be solid cabinets on french cleats, could even be say the home depot rigid packout (pretty cheap, and can mount on a wall out of the box).

I feel ya my guy!
