It's now permanently mounted on rail's so I can get in about it for servicing. However, it used be on wheels in a tiny Fiat Fiorino... the worlds smallest truck mount? I built it because I was sick of being let down by the poor wiring, connectors and switches in 'regular' machines. I got an old Bane TM, restored it first but wasn't happy. There was only a small space available in the van, so I chopped 80% off the freshwater side and 40% off the waste side and had it welded back together. I squeezed in a 600psi Cat pump, a Mytee pump out, cooling fan, in line heater, and 2x 6.6 vac motors. I used only straight pluming on the vacs, and I rigged an auto fill and empty system and chemical feed. The crowning glory is the wiring. I only use low voltage switches, they power big contractors, which turn the units on and off. The paint is a powder coat. Cable one powers one 6.6, Cat pump, pump out and fan. The second powers the second 6.6 and the heater. One problem with the straight plumbing was the velocity, the waste water came in so fast that it didn't fall, it went straight out the vacuum pipes! I fixed that with a Mytee inline heater, it was a good idea for the lint anyway. It took a long time to build. It also cost a lot to do, the wiring alone was a small fortune. If I wanted another one I'd probably commission Chris at Altec to build it in one of his cases. I've used Steamway and Hydramaster TM's in the past, they were awesome, but I prefer using the ETM.
