Hi, Dustin,
You can hardly make Amerigo windows bigger! They are among the biggest out there now, leaving precious little interior wall space for, let's say, simply leaning back against a wall! Sure, the views are great--yes they are--

but really, the outdoors is right there if you need even more views! It all very much depends on how much work you are ready to do and how much money you want to spend. Start asking at other window and RV places and you'll soon get a list of "where to finds." Machine shops can often fabricate things. Those little push-posts can be replaced and riveted on, I've seen pictures on FGRV of replaced ones. If I were going to replace them, I'd make them a tad longer and notch so you could push the window open a little more...though at some point the thing will then just unhinge and
fall out,

as they're designed to come out/off fairly easily for cleanng.
We were having a lot of trouble with our original windows sticking and jamming (and you don't want to force them beyond a certain point!)

but were told a variety of ways on FGRV to thoroughly clean and possibly lube them. We used what we had from the list and voila, get enough oxidation and dirt off aluminum and whatnot, and it slides again! I even used buttonhole thread and literally sewed the rubber gaskets back together where they had shrunk inches apart. Eased it into place and it worked!
We're living with the minor crazing and cracking and crackling and occasional starbursts--(nothing
leaks through anywhere, thank goodness) with the original plexiglass. We did buy some cute sticker/decals on ebay to cover the original stickers that were horrible looking, missing, or the very worst spots...but you can go overboard. The OP used the simple method of letting single fabric panel curtains stay closed over the windows.
Light came through fine, but you didn't see all the wear and tear. No, that was another small thrill we had when we got home.
I'm hoping Paul will put in a plexiglass panel over the narrow, long back window so I'll feel better leaning against it like a couch back...yet another spot where more wall and less window might be handy, really. I assume if you kick that window hard enough it will pop out for egress in an emergency...
Another thing to think about in terms of kicking out windows is why are you allowing flames inside your trailer at all? Not a lot of
escape routes just in case. Peanut had half-burnt candles everywhere inside; mostly, we discovered, to try to obscure the stench from a rotting floor, bottomed and hidden by a "bathtub" hull and covered with brand-new Pergo laminate that hid the spongy damage from our not-too discerning eyes.
Looking back now, OK, probably worth it. At the time, one bad moment after another for many months.
But--we didn't have to wait six years to get our egg. We just had to boil it a lot longer than some after acquisition.
Windows--we'll be with you on some of that eventually. Please do tell us if you forge on, how it goes, what you find, what you pay, was it worth it, etc....
BEST
Kai
