Judy, a ranger told me that some of the best tide pooling is on the Schoodic Peninsula BUT it is very "cliffy" and you have to watch the tides as they come up quickly and can trap you out on the rocks. So, if you guys are shore walkers, go early (follow the tide out), enjoy, and take pictures to post if you find really cool stuff. We didn't make it over to the Schoodic so I guess we have to go back sometime.
As for the side slide window, please keep us posted. I've also seen them in other motorhomes and it has a mini-sunroom effect that I like. The Phoenix slide doesn't go out very far so the window might have to be relatively small and located close to the outside wall. We also have those "scissor" supports on the side that may get in the way. I don't know, I haven't checked it out yet. I suggest cutting a paper window to see how big it could be. Once you align it inside, do the same outside (spacing in enough for the outside wall) and see where it all hits. A window on each side of the slide would give you the ability to look back toward your hookups without having to run back to the bedroom windows to check on noises and problems (and your spouse while they hook up or unhook).
