One day, one job
Retrofitted full size steering fluid reservoir from cars with self levelling rear suspension.
It has 2.5+ liters extra capacity. I can now flush without disconnecting pipes -- just suck all fluid out and fill it fresh. Since system capacity outside the tank is less than 1.5 liters, 2-3 changes like this, each followed by a bit idling, will change almost all fluid in the system.
It also fills that empty space to the right of engine a bit better.
