My sincere apologies for not responding sooner…. life sort of got in the way.
I did post pics on this thread, but somehow they’ve been removed. No idea why. Perhaps a technical glitch? A moderator found them unsuitable? No idea. I will try again to post a few pics with this post.
I do know that the windows are removed from outside the van, but access to the screws that hold the clamp ring in place are inside. I had already removed nearly everything from the Roadtrek’s interior before I removed the kitchen window. So, upon thinking about the process, I really can’t see how one would get access to the screws without removing the sink / galley counter. As the bottom portion of the window serves as a vent for the fridge, I’d assume the fridge would have to come out as well to get access, but I’m not certain on that. I don’t remember the fridge being attached to the window, but I think there was sheetmetal that served as ducting going from the fridge to the bottom of the window/vent. It’s been 2 years, so I’m not 100% certain on that.
Again, I do apologize that I can’t be more helpful. I just went nuts and tore the whole thing apart when I saw the bit of rust, the old fiberglass batting insulating the walls, etc. Still not done with the rebuild, but hope to be by this summer.
