SD is NOT the only one with quality concerns about PK's work....just ask around in more places...I ran in to his work while looking at 105Mc Cats...his "forte"...
No quality and no warranty, once it is done, you now own it. No drawings, no directions and no support - this on a a new Gemini...used ones even worse. things like forgetting to make access to critical connections in permanently mounted fridge and
stoves, RV gear that has to be level installed in a boat, won't work unless the boat is absolutely flat..
best of luck
