Hello again.

In the process of sealing up the factory made holes (that were never sealed/foamed), I've discovered some powdery green mold. The mold is specifically behind the shower stall and up one wall that also happens to have a GAPING hole to the outside.

The finishing work on Gateway Campers is absolute trash.

Ok, so I sprayed bleach water behind the shower and into the open spaces of the wall i opened up after wiping away the majority of the mold (I use a mixture of rubbing alcohol and vinegar). The mold is mostly gone from what I can tell. I will seal up the holes to the outside and install a micro-fan to force air through the bottom/back of shower stall and that wall just to make sure there no future issues.

Heres my questions. Am I just getting a string of bad luck because I keep it cold inside and we're in S. FL? Or, is this typical of campers, but it goes unnoticed because most aren't willing to remove walls of their $70,000+ campers? Are there other places I should look specifically that you've seen or heard of before?

O3 Works wonders. Nothing lives after a good dose of Ozone. Run your A/C to thwart Legionaires like pathogens.

Most don’t look for mold. Once it is pronounced they react.

Dont use bleach and vinegar together, ever, even if just wiping one and spraying the other. Dont want you to die yet.

Are you sure it is mold?

A copper pipe in the area will get some normal discoloration and even some green powdery looking stuff as a by product of copper oxidation.

Despite popular belief, spraying bleach doesn't kill mold and can actually make it worse. While bleach kills the surface mold, the water in it will feed the roots and guarantee it comes back. All you've really done is disturb the surface. Once mold is in/on a porous surface like wood, it usually needs encapsulated or replaced. You could try an ozone generator but it's no guarantee and they have their risks as well. Mold remediation is an expensive affair requiring HEPA scrubbers and usually replacing the affected materials.

I haven't seen copper piping in a camper. Even my dads $400,000 bus doesn't.

It is all PEX.

True that it is all pex.
The compression rings could be copper.
I'm only suggesting a possibility here. Anything copper can shed a green powder like substance.

Ok, heres the resolution. Again the factory didn't seal the inside from the outside. Where the PEX entered between the shower stall and the wall from the outside wasn't foamed. Humid air came in. was fully trapped in the wall and behind/under/next to the shower stall and condensed on the surfaces, plus kept is super FL humid. There was actual standing water in the spaces from where water dripped from condensation (no water leaks).

I opened the wall, removed all the wood cuttings they left when they made the cutouts for the faucets/floor/etc. Soaked all the water up and put the blower there with the wall panel bent out. Dried all the wood and floor etc. Once that was dried well, I cut the interior side of the wall (behind the shower walls but not visible from the bathroom) to make air channels to fully ventilate both around the shower and in the wall. I also foamed the opening to outside.

I ordered a high pressure micro fan (counter rotating type) that I will install under the sink - which is adjacent to the shower pan - blowing into the enclosed space behind the shower. The air will then travel up and out of a vet at the top of the wall at the furthest point in the circuit. The slow, but constantly moving air will keep the humidity from building up from any remaining condensation.

I think this will fix this issue permanently. There is no more stagnant air to cause an issue.
