Portables are for where the truck mount can't go.If you are feeding it 170 degree water it does help kick it up a notch. I was using 6 flow at the time. TM 6 flow not porty 6 flow. If running a porty get a little giant. You are not going to heat ice cold water with 1500 watts. Its hard to make any money unless you have a good machine IMO. Portables are for part time cleaners and high rise IMO
