Bubbling on interior ceiling membrane

Hi all,

I am perplexed as the bubbling is getting worse on the interior ceiling.

Although no water has been discovered I am perplexed on the source of the problem.

We do live in Northern California (bay area) and I leave the pop up truck camper in the lifted open position quite a bit when it's stored. We also leave a window and a skylight open.

Could this be moisture from the air causing this?

Would we be better off closing it up when storing it for more than a couple of days?

We were thinking maybe it was heat that was causing the bubbles but now I am starting to think maybe moisture in the air can be contributing to this issue.

I am looking forward to your responses on the source or cause of this issue and then secondly how any of you have remedied the unsightly problem.

Of course I do not want to fix until I know what is causing this.

Thanks much for you insight and I have included a couple of images as well.

Could be almost anything. Is this a new rv?
Since it's on the ceiling, it could be water damage, but if you're in a dry area and had not rain, that's not it.
Could be that the glue is failing due to the heat. If you could store it in the shade, that would help.
If you think it's moisture from the air, get a couple of buckets of DampRid and close the camper up completely to store. DampRid is environmentally safe and the pellets will turn to water as it absorbs moisture.

Welcome to the forum.

Hi there Reverse,

It is a 2015 Palomino. I was thinking possibly heat causing that as well.

What is the best way to get rid of these unsightly bubbles?

Please share your experiences and any specific materials that should be used to prevent this from happening in the future.

In my 2021 the ceiling material is sheets and there are spacers or trim pieces that keep it up. You can remove those spacers and the sheets will actually come down.

From the pictures your looks like some king of laminate. Is that right?
