I have one of the newer ones. Bought it in October of last year. I have about 430 hours on it right now and I haven't had any problems with it. The new chevy has a drive by wire throttle no cables and it hooks into the electronics through a module. Very nice design for fuel savings etc. Anyway it has good suction and very good heat with the salsa, I can run a tile tool at 700 psi and it will sustain 215. Using a wand no problem to keep 230+. It is not a dual wand machine but there aren't really any true dual wand machines that run off of a van. If you want one of them look to
vortex or aerotec. If I were to buy again I don't know if I would of bought a
butler or a slide in instead, possibly in a tall sprinter so you can get in the van and stand up, although I've heard reliability problems with the sprinter. The blueline thermal wave 2 seems like a very good machine and the
prochem everest. They both have bigger blowers but still I don't think they are very good for dual wanding. You may have some fuel savings running them however.
As far as the
cds I've ran 200 ft of hose and it seems to do good but it leaves a bit more moisture on the ground than I'd like to but for 150 ft of hose or less the machine does fine. Do yourself a favor and get a better wand than the hydrahoe. See if you can apply the value to something else.
The main reason I didn't go with
butler was because there was no local person to repair it if the need were to come. Sometimes I wonder if I would of been better off since they have better financing. If you can get their financing it makes it a good bit cheaper to buy a
butler. If you have any specific questions message me and I'll try to help you out if I can.
