I've tried various "solutions", including fancy-pants trolleys with wheels and drawers, but keep coming back to the $20 steel box I bought decades ago. It contains everything I need to build a bike from the frame up, except for my VAR headset cup press and the work stand. It always comes with me on cycling vacations (in the car, that is) where the bike rack doubles as my work stand if needed.
It also enables me to move my work space around the house or garden, depending on weather, mood or heating requirements.
