Why Humidity Is A Problem In RVs?
RVs should be comfortable spaces. Unlike other vehicles, you can actually live in an RV. Hence, many outdoor enthusiasts and survivalists often use their RVs as long-term residences. Some even converted them as homes.
Either way, you have to guarantee that your RV is livable. It should be as comfortable as your house. And to do that, you have to ensure that its internal humidity is properly regulated. You see, when humidity exceeds 60%, the ambient air feels damp and muggy. And despite being damp, the temperature feels hot.
Well, the reason for this is that high humidity prevents sweat from evaporating. It causes you to sweat, but the latter doesn’t evaporate, which makes things extremely uncomfortable.
Humidity can also make your RV smelly. The odor becomes musty, especially if molds start to grow inside your vehicle. Overall, prolonged humidity can cause damages to the furniture and paint of your RV. If you don’t want to deal with expensive repairs, you have to control the relative humidity of your space.
How To Choose The Best RV Dehumidifiers
Dehumidifiers are an effective option in combating high levels of humidity. It is a worthy and must-have investment in RVs, campers, and trailers. They are the ones that ensure that the internal moisture remains cool and dry.
Size of the RV
However, not all dehumidifiers are suited for RV use. For instance, we have to indicate the size of these dehumidifiers to the size of your RV.
Class A RV has a length of 33 feet. Meanwhile, Class B units are 20 feet long, and Class C motorhomes are around 28 feet. Their average width is approximately 8.5 feet, with an average height of up to 14 feet. Taking these things into account, we can say that whole-house and commercial dehumidifiers might be overkill for motorhomes and RVs.
Of course, you are still free to get these large dehumidifiers in your RV if you wish so. But if you mind the power consumption that these devices have, you can guarantee that they aren’t the most energy-efficient option out there.
In fact, the following table emphasizes that it is not always ideal for getting large dehumidifiers for your RV. Even the portable ones can already deal with the moisture problems that are lingering in the vehicle.
Noise
I also have to indicate that noise is an unwelcome guest in any RV. Unless you made your RV a party platform, it should always remain as silent and cozy as possible. In this way, the residents will experience a noiseless environment.
You also have to remember that these RVs have closed spaces. Hence, it is easier for the noise to get amplified. If you get a noisy dehumidifier, you’ll eventually have to deal with cacophonous disturbances every day.
That’s not something you want, right?
Water Tank Capacity
Since our preference is a portable and compact dehumidifier, it is understandable that their tanks don’t have a vast capacity. But at the same time, we don’t want it to get full after an hour or two. That’s not practical. It would eventually mean that you have to drain it frequently. It could disturb your sleep or any period of rest.
You should always opt for dehumidifiers to have a decent tank capacity. It’s a needed aspect that completes the ideal ergonomics that every dehumidifier should have.
Conclusion
The best RV dehumidifiers are crucial appliances for motorhomes, campers, and trailers. You have to expect that humidity may become an issue eventually in the vehicle. These devices ensure that you wouldn’t have to deal with the problem extensively.
In the long run, it would preserve the structural integrity and convenience of your RV.
