Mold issues?

[Petrovsky]

No mold for us in the shower either

After 1 year of use, I noticed some small spots of mold under the mattress, just received a new bed and have the Hypervent coming this week should address that issue

While camping in the Pacific North West in Sept through early Nov last year, tons of moisture inside due to the heater running and cold outside temps, we did see some mold starting on the inside of the windows... had to wipe them down every couple of days

Good luck and enjoy

Concerning your issue with mold on the mattress. I did see a post somewhere with the same comment and similar conditions. The point that made sense was that the storage area under the bed gets cold and the bodies on the bed make that a hot area. They noted after lifting the bed that the underside was quite damp. Their solution was to drill out 2 4" circular holes in the base on either end and place a vent cap there. They mentioned that it solved the problem by allowing air to circulate in the compartment.

I thought it was a good idea although I did not experience this issue. I went ahead and did the work as well. Local shop had two light brown vents and it looks great. Never noticed any issues.

Another point: I am considering going to lithium and eventually inverter, panels etcetera. Two locations for dual lithium batteries. First would be on the tongue but likely the best location would be under the bed, shorter cable length and a heated area now vented a bit. Likely will install there when the Boss approves the budget!

New to Grand Design, but have been RVing for 35 years. We have a 2023 imagine 2500RL with the walk thru bathroom. Shower stall has the “squeegee” sliding enclosure. Concerns for mold/ mildew. Have not taken “shake down cruise” yet 😊

We have the same shower screen. During our 4 month trip last summer, the bathroom started to have a moldy smell, and toward the bottom of the screen there was a discoloring that started to appear. We cleaned it and then started leaving it closed after our last shower of the night so that it dried completely. No more issues.

Hadn't considered venting the storage under the bed, I might do that as well

For now, I just installed the Hypervent product that goes under the bed, 3/4" loosely woven plastic to help with airflow... see how it goes

Thanks for the vent tip

Some models have vented bed storage. On both of our Momentums, the bed storage was vented. I can't recall if our Reflection had vented bed storage, we didn't keep it very long.

I have to tell you after all the years of RVing, for the first time I installed a good marine fan up on the wall in the corner of the bathroom on our 22MLE. There isn't an A/C vent in the bathroom so I thought this would be good for cooling off after a shower. But we also added one of those retractable clothes lines in the shower so we could hang our towels and wash cloths in there to dry using the fan. It keeps the moisture down, dries the towels, and we realized we could also pull the retractable shower door out and point the fan to blow over the top of it. That way the door dries out along with everything else. I'll be doing that in the new 23LDE this spring.
We have a few of these fans for our boat and RV, not cheap but the push more air than typical 12v fans of the same size. Obviously, you can get much cheaper fans. I see they raised the price $15 since the last one I purchased. If you have a wall switch for the light or vent fan you can tie into that if you mount the fan on the same wall. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

We use the under bed plastic material and never have any issues either. In fact, we never had any without it.. just did it cause heard of those with issues and its cheap insurance.

In our 295RL we have a ceiling AC duct. Usually keep it closed.... we always use the ceiling fan/vent when showering as it gets rid of all the humidity after a shower within 5 minutes.

Thank you for the replies. No mold or mildew, just concerns that enclosure will not dry out completely. I always keep the bathroom vent open. I have a shower rod and curtain is needed.

Hi! Had one of those shower doors in our 2019 273 MKS for two years and had no issues. We would keep it closed after every use until completely dry and wipe both sides down with vinegar/water solution about once a week. Once that's dry, put it away. Never had an issue with mold or odors.
