I spent about 3 days doing the install but I spent a lot of time double checking and making sure I was doing everything right. My DW helped me with fitting the cu in place and my DB helped slide it back in place. The cooling fans were mounted different and the fire box was a little different, but a call to David Force at rv cooling unit warehouse got me back on track. If does come with some difficulty,but it is mostly physical.The technical part was being sure that you mark ALL wires and seal the unit in place. I am far from a mechanic and 69 years old and I made it fine.
I finished my installation on my Norcold 1200 and it is cooling very well. It has been running for 5 hours and the temp is 25 deg. in the freezer and coming on down. The outside temp 93. Thanks to all who posted on here, because without your help I could not have done this.
My Amish unit will be delivered in the next couple of days. After reading for hours and watching several you tube videos I have talked myself into doing the install myself. It looks pretty simple but I am still nervous.
