Personally i think there comes a point where you have to switch from a porty to a proper TM.
I would prefer to have a porty which if needed, could be wheeled off the van and taken to the area which needed cleaning instead of long hose and power cord runs.
An engine provides all the power to run the pump, blower and of course heat for the HX...
With this and any other ETM you have to add some kind of HX, and if mounted in the van will require fuel the same as a regular TM.
I really like Mytee products but im doubtful this will be very popular when lets face it machines like the Jag, Storm and Enforcer are a fraction of the price and will essentially do the same job and allow the operator the flexibility of removing from the truck.
Just my opinion
