Bob, I have only owned
ProChem units because they have an aluminum frame (I was told that
Hydramaster is iron) and my distributor told me that they seem to be the most reliable and provide strong customer support. I have a Peak as well as an
Everest 650HP.
I recently bought a Dodge Sprinter in order to set it up with a portable for duct cleaning, upholstery cleaning and some carpet cleaning. To my surprise, I have been able to modify the portable to have enough vac power that I can clean carpets with it and get about the same results that I get with the truckmounts. The portable I have has about an 800 PSI pump, three 3 stage vacuums inside and an additional 3 stage vac booster that replaces the screw on lid. It has been an overwhelming joy and success to use. I have a Pile Lifter vac in the van as well as a new RV360i. The Sprinter gets about double the fuel economy that my GM vans get (I have two GM vans with the tm's in them) and because I am not using a gas powered truckmount when using the Sprinter, it is saving me loads of money each week. The Sprinter gets nearly 30 mpg highway, 24 mpg overall. It is an amazing van and I will NEVER buy another american made van as long as these are available in this country. The quality of driving is amazing, great steering precision, handling, turning radius, road feel, visibility, comfort and so on.
I cannot compare truckmounts since I have not owned other brands but the Prochems have been very reliable with their only shortcoming being the short lived belts.
Dual wanding with the
Everest can be wonderful on the right jobs but they are few. It's a nice setup to have but not to use everyday.
If I were to add a 4th van, I am not sure which way I would go but I would probably add another Sprinter/ portable setup or maybe a Genesis/Sprinter. Right now, I have enough truckmounts for my business so I don't think I will be buying another one very soon. I have about 5 RDM's, 3
RX20's and one RV360i that I just bought a few weeks ago.
I don't sub any work out and gear my business for a top quality image. I am completely honest with my customers and it works out very well. I don't feel that there is any need to play games or deceive consumers to make money.
