ya I don't think that was factory, its using gear clamps. normaly the factory still uses crimp fittings when they use the wrong tubing haha.
I have very minimal "Non" pex in my cougar, I was surprised, and it is all where it is easy to get at like under a sink or what not. It is on my list to change out to all pex and the proper coper ring crimps not the little end crimps they like to use, but I want to totaly redo the truck camper first as I think it is all the grey polly B or what ever it was they used in rv's in the 90's. its small, restrictive, and uses rubber compression for sealing that is a pain to work with and prone to leakes.
I am not sure I would ever want shark bite on a mobile instalation, heck I don't even like them in a home, they are the most prone to leaking of all the "pex" fittings, but I can see why people use them, aside from being easy you don't have to buy the expensive crimpers. I still like my good old copper ring crimp, but I do have the different tools for doing it, including ones that are made for tight spaces.
