Is there another fastener that can be used? The metal staple that is attached into the aluminum frame transfers the cold straight to the inside and ices up.

Thanks for the idea rando. I bought some 1/8" foam, based on a comment in one of the threads I linked. It sees ATC uses this now on the rails themselves.
I had thought of buying 4' wide reflectix and installing that over the whole surface, taping to keep the vapor barrier intact. I see no value in allowing warm/wet air to flow into the insulation. My house has a vapor barrier, so why not the camper?
I like that the Aerogel is flame proof. I see it is hydrophobic... is it also non-porous? How would you seal the edges together?
Hadn't thought of ensolite either. Hmm... sound barrier too.
Good ideas for sure!

The aerogel is porous - it is glass fiber batting impregnated with aerogel particles. Honestly it is not really a reasonable solution, given that it would be right next to the uninsulated soft walls, but it is fun to dream.
Ensolite would probably work pretty well. It is a cheap way to get closed cell foam with a sticky back. It would work as a conductive barrier, a moisture barrier and it is easy to apply and available in multiple thicknesses.
Refltectix is probably not the right stuff for this application. It is primarily a radiative barrier, and needs to have an air space on at least one side to work. It won't do much sandwiched between the headliner and roof, unless you want to leave it exposed. I am not sure a silver bubble wrap ceiling will compliment your beautiful wood work.

No air space? I was thinking the reflectix would go over the rigid foam, between that and the cloth headliner. Lots of reflective air space in the camper.

If you cover it in a cloth headliner, then it is no longer reflective.......

Doh.... I had assumed the headliner would be "transparent" to reflective radiation. Hmmm.

It depends on the cloth and wavelength. But generally speaking, the cloth will absorb some/most of the IR radiation and warm up - at which point the heat transmission is conductive, not radiant. The general advice is that you need at least a few cm of air between a radiant barrier and the nearest surface for it to work.
This point seems to be lost on a lot of folks - one of the pop-up manufacturers (can't remember who) was putting a radiative barrier inside their soft walls for an 'arctic option', which clearly would not work.

OK, so before tackling the install of a new headliner/patch, I have to straighten the roof. Previous owner claimed the roof "popped up on its own" while driving down the highway. Uh huh. Probably forgot to do the front latches, or tried lifting it without undoing the side latch. Many folks here have been there!
First things first, removing the 330w solar panel
OK, so I laid a 2x4 down on the area to assess the bend.... it doesn't look so bad
Until you get the bigger picture
I tried the Bill's method to straighten the roof,
but didn't have a C-Clamp big enough
Then I tried radarcontact's method,
and couldn't get the roof to budge, even with bouncing on the roof with my 200 pounds.
So then I tried Vic's method. A stack of leveling blocks, a 2x4 and some towels to prevent damaging the interior finish or headliner.
I wedged the 2x4 in tight, and then applied my weight strategically (as in the radarcontact method) to bend the roof. I had to reposition the 2x4 a number of times to gradually bend out the roof evenly.
Final result

So, on first look at Vic’s method, I had a serious mental physics disorientation on the nature of natural forces near Calgary. Then I thought you wet the towel and left it draped over an upright 2x4 overnight in an unheated garage before use.Then I suspected you had access to some seriously powerful laundry starch. Finally, I realized that that image was to be viewed while using the Teeter Inversion machine.
Seriously, this “Hunker Down at Home” social isolation may result in the loss of my sense of reality.
The results of Vic’s method look like the did the trick.
Stay safe

Vic,
if you need any fine tuning, I’m thinking you could try a bar clamp on both sides of the bend, with your board spaced in between, might be worth a try. That would give you the clamping distance you need and is fully adjustable, and should provide needed force to bend aluminum square tubing, ever so slightly, without overdoing.
