Good points Jerry I'm for keeping OE except the in my opinion valid point of needing a dual master cylinder. Then which side do you connect the hydrovac to and or add a second hydrovac? I don't have a spare to add to the system do you? Additionally my hydrovac needs a rebuild that in my research I've found to be around $400. At which point a dual master cylinder with a hydraulic booster is sounding pretty good. I intend to use it generally as a beefy 1/2 ton truck but am not opposed to the occasional parade and I lack the yeti full of beer but have found that a $14 cooler from Walmart keeps them from rolling around in the bed just as well and if they get hot i figure I didn't drink them fast enough.
