I have never pulled a window in an RV but I have done some extensive repair on old wooden boats year ago. I would cut the caulk around the window with a razor and remove it being very careful to not damage the frame. Inspect the plywood inside the frame area and if you have an inspection camera you could thread it down between the inside and outside wall to look for mold or rot. If you dont have one pick one up on Amozon that connects to your laptop USB port for $15-$20. If you have a sheltered place leave a fan blowing in the cavity to dry it out. If you see rot down inside take it to a pro. If you just have some bad wood near the frame get a product called Git-Rot. You inject it into the wood and it hardens stronger than the original wood and is impervious to water. Of course reinstalling the original window is the easiest option but you could have a fibreglass man patch the hole but expect a bill in the thousands for color matching gel coat and forming the fibreglass to look seamless.
I do have to, at some point remove the window, as parts of the wood underneath is rotten. That is my issue: how much of the wood against the front wall and around the window do I need to replace, and how to replace it. This is beginning to sound like I will need a professional who has done this before. It is not something I'm going to do quickly, that is for sure. Thanks for the idea.
