It gets hot under the bed cover.

I turned the temp down and it seemed to stabilize it. Just glad it wasn’t the truck or tonneau.

any chance the set screw is loose?

Wonder if there's a difference with the hollow, double wall retracting covers? In theory, the air-gap between the outer surface and the inner surface might potentially keep some the heat from transferring below the cover. By no stretch of the imagination is it a test, but the few times on hot sunny days I've opened mine to pull something out, it didn't seem to have a perceivable difference in temperature from outside the truck. - The top of the tonneau was certainly warm/hot feeling, having baked in the sun.

Now I want to toss a thermometer under there and see what happens on the next hot sunny day. - It's cloudy, rainy, and only going into the low 80s today, and we were low 70s and overcast with showers yesterday.

It may suck a few inches of upright space, but really like my retractable regardless.

For the mirror, never imagined the mirror glue would melt like that! It usually takes a sharp scraper to even remove the hard crust residue before re-gluing the mirror mount back into the windshield. Any chance the Permatex mirror glue is the one that held? - I keep one in the house for a just in case, but haven't needed to re-glue on in years. (Probably just jinxed myself).

I'm pretty sure the Permatex was the one that worked... I had tried a couple different ones from a discount auto store and they didn't hold more than a month each. Each time I had to scrape and clean the glass real good before I tried them. It was a real pain... but so was hitting a pot hole and watching the mirror leap off the windshield!

Too hot to go out and look now. I’ll need to look tomorrow morning. I didn’t even realize there was a set screw but wouldn’t it shake all the time now?

All the covers I have seen are black. Perhaps another color would improve this. But who would want a white cover?

there's loose and then there's loose enough to shake lol. usually, when glue fails it doesn't heal, just spitballing hoping to help.

not my text on photo, read it as tighten this screw.

Throw that thermometer in the cabin with the doors and windows closed and you'll see the same or higher temps, but here the black tonneau cover seems to be acting like asphalt and absorbing radiation (think car races where they say air temp vs track temp.)

Yes. As hot as the bed gets, I think you are right that the cabin gets hotter.

I think my bed cover has some sort of insulation between the two layers of aluminum that make up the panels.

A lighter color would help but black matches the trim.

Oh. We're talking about current events and truck bed covers. With a thread title like this one can easily get confused.

Found this strange, replaced my bed cover with solar panels and the temps underneath was ambient, 270w being generated, NOT heating under the bed cover.

Aluminum diamond plate on iconic silver looks nice but gets very hot in Texas summer too.
(My oldest brother inherited a black dart station wagon with red vinyl and NO A/C when we lived down in Laredo in the '60s.)

Funny how times change. In the 60's very few cars had ac or power windows. Seen many cars back then with aftermarket ac installed.
