I to have to share your love for Systainers Brendon and the hassle of going back and forth to the Van.
Also being an Audio Visual installer i also needed to become more efficient with my time and converting to the Festool system has achieved that for me, as well as finding a new obsession.
I added the Ct26 recently and why did i rule this out when buying my first Vac.... maybe it would still be my first vac if i hadn't..... simply awesome.
Oh and the best part of the change i now have room to move in my Van and i don't have to fight to find something.
