Dealer installed a/c

[jlmerie]

I have seen a lot of discussion about aftermarket a/c but can not find a discussion of the usefullness of an a/c system that was added years ago at the dealer. Has anyone removed one of these systems from one truck and added it to another. I have access to a very complete dealer installed system but would like to know how well this works. It seems to me that it would be much cheaper than one of the new aftermarket systems. The one I am looking at is currently installed on a truck. It works and blows cold air so I know that part is ok. How involved is the installation? It would seem if I took a lot of good pictures before removing the old system that it should be fairly straight forward to install on the other truck. Of course I would keep the system sealed so I don't have all those worries. I am sure someone has done this.
