Ok. Where to begin.
"Ok. Where to begin. First off the design of the unit is well thought out and nothing was over looked; the outside door screws into the frame from the outside so you don t have to worry about finish issues; when I ordered I had to order the 18 door and beauty ring; as well as the filler blocks. The screws secured it beautifully. It came with the insulating tape too! Swapping the door was easy; and connecting it to the rv was easy; I had to redo most of my pex there but it s expected when upgrading things; I also added a pressure gauge on the cold side to be able to monitor it. My only complaint currently is the controller cables were short; so I had to expand those with more wire. But everything on my rv (gas line; water lines; and 12 volt all) were easy to install."
