You know, I gotta' say you could not entice me to give up my 33 year old slide-in, because it out-performs other truckmounts to the point I am able to run dual wands 300' from the van (that's 600' of vac hose), blistering heat, and plenty of flow for #8 and a #6 wand, with reliable APO. All this is accomplished using a Roots #45 blower, a Cat pump, and a Honda GX-670. I have replaced 4 motors, had one rebuilt, am on the second Roots #45 blower, and am using the original Cat pump which has been rebuilt a few times over the years by me. How much money would you save if you never had to purchase another truckmount in over 33 years of cleaning, and still had your everyday machine as powerful as you would ever need? MAX AIR, do you clean now and need a dual wand machine, or are you just thinking you need one? Have you run a dual wand machine before and that's why you want one?
