Mark.... The expert/dispatch/scudo are cracking vans. Plenty of guys use them on here (including me as you know). I have a 400L tank and have never ran out of water. I dont use a tap / trigger at the moment, i just use the controller. So i waste a bit of water.
Hows the system going anyway ?
A vivaro is good, but big. Brian Stubbs round the corner runs one but he only does commercial.
its going pretty well am gettin used to the pole a bit now aint lost any customers yet and no complaints yet,
think i'm out growing my astra already though!
