A mate of mine purchased a scorpion about 5 weeks ago. He loves it !
He had a ninja before, says the performance is FAR better.
He uses it truckmounted, with a flat type tank for fresh water and the proper scorpion Aux waste tank.
Hes got it fitted in a Scudo, i will see if i can get any pics.
He also carrys a dry solvent machine and dry fusion set up, all on the van at the same time !
He says that at 75ft he cant tell any difference in suction than at 25ft.
Also when using the Aux waste tank he doesnt notice any drop in power.
He uses a ashbys steammate for heat, but fills up the tank with hot water in the morning and so often doesnt need to use any form of water heater..
