RV mold and ventilation in winter
Out of the blue RV mold and ventilation became a topic. My daughter called me the other day with a question about her new to her RV. This is their first rainy season with a hard-walled RV. They had locked up the RV tight with all the windows and vents closed. They had not gone into the RV all winter and when they opened it up they found 2 small patches of mold. She had a good plan for removing the mold. She wanted to know how to keep the mold from reoccurring.
Starting with the most simple solution I thought about the need for ventilation and keeping humidity levels low thru air recirculation.
I asked her if she kept a window or a vent open so that air could circulate within the RV. She told me that she was concerned that an open window would allow rainwater to enter the RV. So with that mindset, they had everything locked up tight. I informed her that this decision was most likely the cause of her problem. She would need to keep a window or vent cracked open so that air could circulate. I informed her that I always keep several of my roof vents open on my RV for just that very reason. Also when cooking I always keep a vent open to help remove the humidity that cooking brings into the rig.
That’s when the hammer came down on this old head that they might not know about roof vent covers and what they do for your RV.
Vent Covers at Amazon.com
Why Do I Need Vent Covers?
I love these roof vent covers. They have relieved me of a lot of work on the RV and at the same time prevented stale odors and mold from growing within my RV. Let me explain.
Roof vents in RVs work really well at venting the RV of everything. Cooking odors, pet-related odors, hot air, and humidity can be released quickly just by opening a vent and a window. It’s just a regular jet stream of air moving thru the RV. I may have exaggerated on that jet stream remark.
But, the best thing I like about these covers is that they protect my vent lids from being rotted out by the sun beating on them. Prior to getting a set of these vent covers on my RV, I was resigned to the fact that I would need to replace my vent lids every 3-4 years due to sun rot.
Ingenious mounting
I was originally resistant to these covers because I thought that I did not need another set of holes in the roof to mount the covers. Boy, was I wrong about the mounting. The cover mounts to the roof vent along its vertical surface. Any chance of water infiltration is virtually eliminated. The following 2-minute video shows you just how easy it is to mount these covers to the RV vent.
Self-locking Nut Definition
A locknut, also known as a lock nut, locking nut, prevailing torque nut,[1] stiff nut[1] or elastic stop nut,[2] is a nut that resists loosening under vibrations and torque. Elastic stop nuts and prevailing torque nuts are of the particular type where some portion of the nut deforms elastically to provide a locking action.[2] The first type used fiber instead of nylon and was invented in 1931.
From Wikipedia, the free encyclopedia, https://en.wikipedia.org/wiki/Locknut
The only thing I didn’t like about the vent cover is a personal preference of mine. I like self-locking nuts over nuts with lock washers. Self-locking nuts will not loosen up, ever. Vibration over time will loosen the tightest nuts, even those with lock washers. I didn’t want to loose a cover due to vibration. Also, I did not want to schedule an inspection for loose bolts and nuts on my vent covers so I substituted self-locking nuts for the nuts with lock washers.
