The Top RV Dehumidifiers: Small & Portable Motorhome Dehumidifiers

Looking for a dehumidifier for your motorhome or trailer? Look no further, we’ve put together a comprehensive list for you based on the best reviews from other RV owners like you. (And no, you don’t have to buy your new appliance from Camping World… you can get it online at Amazon!)

Unfortunately there is no such thing as a 12 volt dehumidifier specifically for RVs, but there are plenty of miniature versions that only take a small amount of energy, which your RV will be able to run either off solar if you’re boondocking or off park electricity if you’re plugged in at a campground.

Now, the best RV dehumidifier for your needs will depend on a few things.

How much humidity do you have in terms of both people and weather, and how big is your RV? The more humidity and space you have, the more dehumidifyng power you’ll need. In fact, you may need more than one small dehumidifier to keep your whole RV dry and free of dampness if you have a very large space or many people.

If your RV is on the smaller side, some simple drying crystals may be all you need to suit the humidity in your rig.

We cover all of the options below!

hOmeLabs 4 Gallon (30 Pint) Dehumidifier Energy Star Safe Mid Size Portable Dehumidifiers for Medium Large Spaces up to 1000 Sq Ft with Fan Wheels and Drain Hose Outlet to Remove Odor and Allergens

  • 4-GALLON LARGE DEHUMIDIFIER: If your standard unit of measure is ice cream, our dehumidifier removes up to 30 pints from the air per day. But we measure in gallons (because we're talking about water) to make the capacity easier to comprehend. This moisture-sucking beast is fit for any basement, cellar or large room, and it's Energy Star certified, so it quickly and effectively absorbs moisture without racking up your energy bill.
  • DESIGNED FOR THE MODERN HOME: That most dehumidifiers are clunky eyesores is news to nobody. We designed with the modern consumer in mind: a sleek, clean look our customers love, convenient built-in wheels and handles, and a quiet fan that won't drown out your current binge-watching obsession. Durability is key, too, which is why we offer a 2-year warranty, plus an extra 6 months if you register on our website.
  • SUPER EASY TO USE: Dehumidifiers don't need to be complicated, so ours isn't. Adjust to your ideal moisture setting, then let it run its continuous 24-hour cycle until the tank is full, at which point it will automatically shut-off. Don't got time for that? There's also a drain hose outlet for continuous draining. The hose is not included; we recommend a ⅝" diameter garden hose with a female threaded end, and optionally Teflon tape for extra security.
  • ELIMINATES MOISTNESS, ODOR & OTHER THINGS YOU HATE: Moist is a bad word. Our portable humidifier reduces odors and allergens by removing bacteria from humid air through its built-in pump compressor. It also features a turbo mode that increases fan speed from normal to high for maximum moisture removal and odor reduction.
  • IMPORTANT THINGS TO KNOW - Dehumidifiers emit heat when in use (that's how they absorb the moisture). This product won't work in the same room as an evap cooler, and is intended for spaces up to 1000 SQ FT. It measures 15.2 x 10 x 19.7 inches, has a .8 gallon (3 liter) water tank capacity, and removes up to 4 gallons (30 pints in beer measurements) of moisture from the air per day.

For very large RVs, toy haulers, and fifth wheels that are plugged into park electricity in high humidity areas, this will protect your RV from must and mold.
