That is my guess and it's not just the contact paper being installed wrong.
I really wish you were not correct so often, Iggy.
It's been raining here for four days and I've had the slides out while we prep for a trip. I walked into the motorhome today and noticed a small amount of water on the dinette cushion (a different slide than before). Yup, I now have a small amount of the same bubbling on that slide's trim and there were slow drops of water coming from a separation in the underside trim.
I looked on the top of the dinette/recliner slide, the biggest one and the only one where the topper sags from water accumulation, and there was a lot of standing water.
I ran the slide in and the standing water pretty much stayed on top of the slide instead of getting wiped off. I used two bath towels to sop it up a few hours ago and the dripping immediately stopped so hopefully I caught it quickly.
I looked closely at the top edges and I can see that FR used some tan caulk that has shrunk. I'm guessing the standing water finally pooled up to where it found a gap in the caulking.
Some people with a 2019 have reported they have a tape on the top of the slides at the edges but I do not have that; it's just a small amount of caulking at all edges.
I'm going to use a hair dryer to warm up the edges and the trim inside where the water was seeping and then apply a liberal amount of caulk on all four top edges on all three slides, as far as I can reach under the topper. Then I'll run the slides in and see if I can reach any more.
The kitchen slide on the opposite side had no standing water on the top so it's not that water was blown underneath the topper by the wind. The bed slide had just a small amount of standing water.
Since the dinette/recliner topper sags so much I'm wondering if the water is coming off the topper at the low point, doing a 180 and running along the bottom of the topper and then dripping on the slide top.
The good news is that the previous bubbling has not increased at all.
If it ain't one thing it's another. Again. <sigh>
