Why Breathable Covers Prevent Costly Mold Damage
The real enemy of a stored RV isn’t just rain—it’s trapped moisture. Your 5th wheel is essentially a sealed box. As outside temperatures fluctuate, condensation forms on the inside and outside surfaces, just like dew on the grass.
A non-breathable cover, like a standard plastic tarp, is the worst thing you can use. It traps this condensation against your rig’s siding and roof. This creates a dark, damp, stagnant environment, which is the perfect breeding ground for mold, mildew, and fungus. Before you know it, that moisture is wicking into your walls, causing delamination and wood rot.
A breathable cover solves this problem by acting like a high-tech jacket. It’s made of materials that allow water vapor (the condensation) to escape, but repel liquid water (the rain and snow). This constant air exchange keeps the surface of your RV dry, stopping mold before it ever has a chance to start. Investing in a quality breathable cover is an insurance policy against catastrophic water damage.
ADCO Designer Series with DuPont Tyvek Top Panel
Protect your fifth wheel with the ADCO Designer Series cover, featuring a breathable DuPont Tyvek top to reflect sunlight and keep your RV cooler. Its Slip-Seam strapping system ensures a snug, wind-resistant fit, while durable polypropylene sides offer all-climate protection.
ADCO is one of the most recognized names in RV covers, and for good reason. Their Designer Series leans on a proven material for its most critical component: the roof. The top panel is made from DuPont Tyvek, the same stuff used to wrap houses during construction.
Think of it this way: if it’s trusted to protect a home’s structure from water while allowing the walls to breathe, it’s more than capable of protecting your RV’s roof. This material is incredibly water-resistant and highly breathable, offering top-tier protection from rain, snow, and damaging UV rays. It’s the part of the cover that takes the most abuse, and ADCO puts the best material right where it counts.
The sides are typically made from a multi-layer polypropylene, which is also breathable but lighter, making the cover easier to handle. ADCO covers also include essential features like zippered panels for easy access to your door, reinforced corners to prevent tears, and a robust strapping system to keep it snug in the wind. They represent a solid, reliable choice that has been trusted by RVers for decades.
Classic Accessories PermaPRO Ripstop Fabric Cover
Protect your 30'-33' travel trailer with the PermaPRO RV cover. Its ripstop fabric shields against water, dirt, and sun, while zippered panels offer convenient access to doors and storage. Easy installation and a secure fit ensure lasting protection.
If you’ve ever had a small tear in a cover turn into a giant, flapping hole after a single windstorm, you’ll appreciate the PermaPRO’s main feature. Its fabric uses a ripstop weave, which integrates a grid of heavier threads to stop tears from spreading. This significantly extends the life of the cover, especially in windy environments.
The PermaPRO is also known for being lighter than many heavy-duty competitors without sacrificing performance. This makes a real difference when you’re on a ladder, wrestling a giant sheet of fabric over a 40-foot rig. The lighter weight makes installation and removal a far less daunting task.
Of course, it includes the features you’d expect from a premium cover. Air vents help reduce wind lofting and inside moisture, zippered panels allow access, and an integrated strap system makes it easy to secure. It’s a fantastic option for those who value a balance of heavy-duty durability and user-friendly design.
Eevelle Goldline: Premium Marine-Grade Material
Protect your pop-up camper with the Eevelle Goldline cover. Crafted from durable, waterproof 600 x 300D polyester with marine-grade straps, it offers superior breathability and sun protection for trailers 16'-18'.
When you need maximum protection, you look to materials designed for the harshest environments. Eevelle’s Goldline covers use a heavy-duty, marine-grade 600D polyester. This is the kind of fabric built to withstand constant exposure to sun, salt, and water on a boat, making it more than a match for a stationary RV.
This material is exceptionally durable and offers superior water repellency. The tradeoff is weight and cost. A Goldline cover is a heavy piece of gear and sits at a higher price point. However, if you store your 5th wheel in an area with heavy snowfall, intense rain, or high winds, the extra investment pays for itself in peace of mind and longevity.
Eevelle backs this up with one of the longest warranties in the business, which speaks volumes about their confidence in the product. For the full-timer who stores their rig for half the year in a tough climate, the Goldline is a top-tier choice that prioritizes ultimate protection over everything else.
Camco ULTRAGuard: Heavy-Duty Triple Layer Design
Protect your slide-in camper up to 18' 2" with this durable, 3-layer polypropylene cover. Features zippered entry doors for easy access and covered air vents to reduce moisture and wind billowing.
Camco is a giant in the RV accessories space, and their ULTRAGuard cover is a popular, well-rounded option. Its strength lies in its multi-layer construction, which creates a system for managing the elements. The design is simple but effective.
The top panel features a triple-layer SFS aquaShed material. The outer layer repels water, the middle layer is a breathable membrane that lets vapor out, and the inner layer is soft to prevent scratching your RV’s finish. The sides are a lighter, single-ply material to enhance overall breathability and reduce bulk.
This cover hits all the right notes for a reliable workhorse. It includes vents to prevent billowing, a fully elasticized hem for a snugger fit, and integrated straps. It may not have the single standout feature of a ripstop weave or marine-grade fabric, but it provides a solid, dependable package of protection from a brand you can trust.
Leader Accessories Cover: Upgraded Windproof System
A poorly secured cover can do more harm than good. Wind can get underneath, causing the cover to flap violently against the side of your RV, which can chafe the finish and eventually tear the fabric. Leader Accessories puts a special focus on solving this exact problem.
Their covers are known for having an excellent windproof strapping system. This often includes more straps than competitors, with tension panels sewn in to help you get a truly snug, drum-tight fit. Some models even include weighted buckles that make it easier to toss the straps under the rig to the other side—a small detail that makes a huge difference during installation.
While the fabric is a competent multi-layer polypropylene, the real reason to choose a Leader cover is for its superior security. If your storage location is exposed and subject to high winds, a cover that stays put is your number one priority. This is where Leader really shines.
King Bird Upgraded Cover: Extra Thick 6-Ply Top
The roof of your 5th wheel bears the brunt of every storm and the full force of the sun. King Bird addresses this head-on by beefing up the top panel significantly. Their upgraded covers feature an extra-thick, 6-ply top fabric.
This multi-layer design provides exceptional UV resistance, which is critical for preventing the sun from breaking down the fabric over time. It also adds a bit of padding, offering better protection against light hail or falling branches. The sides are a lighter 3-ply fabric, ensuring the cover remains breathable where it matters most.
King Bird also incorporates user-friendly features like zippered panels on both sides of the rig, which is a nice touch for accessing different storage bays. With its reinforced corners and robust wind-proofing straps, this cover is built for people who want maximum top-down protection for their investment.
Sizing and Installing Your 5th Wheel RV Cover
Getting the right cover is pointless if you get the wrong size. The single biggest mistake people make is measuring incorrectly. Manufacturers size their covers based on the length of the RV body only. Measure from the very front of the living space to the rearmost point of the body, but do not include the pin box, ladder, or rear bumper. If your rig is 34 feet 6 inches, you’ll buy the cover designed for the 34′-37′ range.
Installation is a two-person job, but it’s straightforward. Before you start, pad any sharp corners on your RV—rain gutter spouts, antennas, and the corners of slide-outs are notorious for tearing covers. You can use pool noodles, foam pipe insulation, or even just some old towels taped in place.
Once prepped, get on the roof and unroll the cover from front to back. Let the sides fall into place, then get down and start securing the straps that run underneath the rig. The goal is a snug fit. You want it tight enough that the wind can’t get under it and make it billow, but not so tight that you’re putting excessive stress on the seams.
A quality breathable cover is not an expense; it’s an investment in protecting the value and integrity of your home on wheels. By choosing a cover that allows moisture to escape, you’re preventing the silent, costly damage that mold and rot can inflict. Take the time to choose the right one, and your rig will be safe, dry, and ready for your next adventure when you return.
