Underbelly has water on the inside cells

I have a 2022 Solitude and had a crack in my front black tank. Luckily, It was very clean and only "fresh" water in it. I had it replaced by the service department at a camping world. Being new to the area, they were the only place close. It was service from hell. They put the underbelly back on and screwed it to the 4 inch drain from all my tanks with six lag bolts. I now have a bigger leak. They fixed it and then I found they didn't secure the toilet to the new tank. I then found they did not connect the black tank sprayer correctly and it leaked. Bottom line, I won't go back. I fixed most of it myself. Anyway, I was doing a check on my rv taking the underbelly off to make sure there was no leaks. As the underbelly came down, there was dripping water coming out. The top of the underbelly was dry. I found that the water was coming from the inside of the underbelly. Has anyone had this happen where the water "inside the underbelly," not on top, did not evaporate? I did a full water leak test and found no leaks. Sorry for the long explanation.

I haven't experienced wetness in the corrugated plastic underbelly, but I have had water get in the underbelly when driving in the rain. I noticed it when I made a stop after the wet drive and the rig was tilted to the side enough for water to drain back out.

So I guess it is possible water can get in the corrugations and then drain. Maybe just keep the bottom off for a while to be sure there are no leaks.

I ended up putting some scrim tape along the open edges where it screwed to the I beam to help keep water out of the underbelly (and from in the corrugations too?).

Thanks for the follow up. I don't remember driving in the rain, but I am getting older. The underbelly has been off for a few days with no water. When putting it back, water dripped out of the cells, that is when I figured where the water was coming from. I don't then the water can evaporate as well when inside the actual cells.

My experience is that If the temperature goes below the dewpoint, you’ll get some condensation that will drip out, especially if you have liquids inside your tank that will hold temperature
