I'm doing some research into building my own skid as I'm not likely going to be buying a $4000 skid, so I'm looking for cheaper options. After pricing out what a hypro D30 pump with regulator costs (Hypro D30 with Gear Reduction and Regulator $888 canadian) then gas engine etc. I can't see how to build one cheaper then Rittenhouse sells them for already made. Electric hose reel is about the same price to. So, is an electric pump viable? does' it run off your truck battery, do you have to have a 2nd battery installed? Pros and cons? Should I stick with shur flo and spreader? I think image is just as important as work btw so I want to look the part if I'm going to expand out spraying.
