If you want superior wind resistance and a complete accessory kit for a mid-sized trailer, choose CAMMOO RV Cover; if you need maximum length capacity, enhanced night-time safety visibility, and a softer interior lining for large motorhomes, choose Xenjum RV Cover 35-38.
• CAMMOO RV Cover: Its biggest strength is the robust 9-layer reinforced roof specifically engineered for heavy snow loads on 24–27ft trailers, with a trade-off being its smaller size range that excludes larger Class A motorhomes. This pick is ideal for owners of mid-sized travel trailers who prioritize structural integrity against harsh winter elements.
• Xenjum RV Cover 35-38: Its standout feature is the extended length capacity up to 38 feet combined with high-visibility reflective strips for nighttime safety, while the trade-off is a slightly more complex strap system that requires careful alignment on very long vehicles. This pick fits owners of large fifth wheels or motorhomes who need extra length and want their vehicle visible in the dark.
The CAMMOO RV Cover is built for the owner of a 24 to 27-foot travel trailer who faces serious weather challenges, particularly heavy snow and high winds. The defining characteristic here is the "9-Layer Thickened Fabric" construction, which isn't just marketing fluff; it explicitly includes two extra protective layers compared to standard 7-layer covers found elsewhere. If you live in an area where snow accumulation is a real threat, this specific reinforcement is the primary reason to select this model over lighter alternatives.
Beyond the fabric itself, the windproof system is aggressive and comprehensive. It utilizes three wide-span straps across the top, four bottom straps that fasten around the chassis, and four buckle straps reinforcing the front and rear. When you combine these eight points of secure attachment with an elastic hem and five vent openings, the design logic becomes clear: this cover is meant to lock down tight and stay there. The vents are crucial because they minimize wind pressure from getting underneath and billowing the material, which is often how covers get destroyed during storms.
Who should buy this? You are the perfect candidate if you own a mid-sized trailer and value a complete "all-in-one" protection strategy. The kit includes tire covers, gutter covers, a ladder cover, repair patches, and even toss sticks for easier installation. The inclusion of a left-side zipper and a large rear panel for loading motorcycles adds practical utility that many generic covers lack. However, you should skip this product if your RV exceeds 27 feet. The sizing is strictly defined for that 24–27ft range, and trying to force a smaller cover onto a larger unit will compromise the fit and the effectiveness of the windproofing system.

The Xenjum RV Cover 35-38 targets a different demographic entirely: the owner of a massive travel trailer or motorhome between 35 and 38 feet long. The sheer scale of this vehicle demands a cover that can accommodate bumpers, spare tires, and awnings without leaving critical areas exposed. This aerodynamic consideration suggests that Xenjum has thought deeply about how wind interacts with longer, boxier vehicles, aiming to prevent the cover from acting like a sail.
Safety and interior care are the other pillars of this design. Unlike some covers that might scratch the exterior due to rough inner linings, Xenjum specifies a soft inner surface to prevent scratches on your travel trailer. This is a subtle but vital detail for preserving the paint job on expensive equipment. Furthermore, the inclusion of high-visibility reflective strips on all four sides addresses a unique pain point: parking safety at night. In dark campgrounds or unlit driveways, these strips make your vehicle visible to others, reducing the risk of accidental collisions—a feature rarely emphasized in standard RV cover specifications.
This cover is best for those who prioritize length and visibility. The ventilation system features six airflow vents, one more than the CAMMOO option, which helps release trapped heat and moisture effectively. The three adjustable zipper doors offer convenient access without removing the entire cover, which is essential when you have limited space to work around a 38-foot vehicle. However, be aware that the installation involves five bottom straps and two extra-long wraparound straps. While effective, this complexity means you need to measure your longest points carefully. If you are between sizes, the recommendation is to choose the larger size for a secure fit, so ensure you have the clearance for a 38-foot cover before purchasing.
• Best for Large Motorhomes (35-38ft): Choose Xenjum RV Cover 35-38 as it is the only option listed that accommodates lengths up to 38 feet, making it essential for Class A or large fifth-wheel owners.
• Best for Nighttime Safety: Choose Xenjum RV Cover 35-38 due to its high-visibility reflective strips on all four sides, a feature absent in the CAMMOO specification.
• Best for Interior Protection: Choose Xenjum RV Cover 35-38 because it explicitly mentions a soft inner surface designed to prevent scratches, whereas CAMMOO focuses on external durability.
• Best Windproofing System: Choose CAMMOO RV Cover for its integrated system of 3 top straps, 4 bottom straps, and 4 buckle straps combined with an elastic hem, creating a multi-point lock-down specifically for 24–27ft frames.
• Best Ventilation Count: Choose Xenjum RV Cover 35-38 with 6 airflow vents compared to CAMMOO's 5, offering slightly more breathability for larger enclosed spaces.
• Best for Complete Accessory Kit: Choose CAMMOO RV Cover for its extensive list including toss sticks, a dedicated storage bag, and specific gear covers for tires and gutters, ensuring everything needed is in the box.
• Best for Car Washing Compatibility: Choose CAMMOO RV Cover if you frequently wash your car under the cover, as the durable 9-layer thickened fabric provides a robust barrier against water runoff and debris during cleaning sessions.
In my opinion, I would choose the CAMMOO RV Cover for most standard travel trailer owners. The inclusion of toss sticks and detailed installation instructions also suggests a user experience designed for ease of use, which matters when you are dealing with a heavy-duty cover.
However, if your vehicle is significantly longer than 27 feet, the math simply doesn't work for the CAMMOO, and the Xenjum RV Cover 35-38 becomes the only logical choice. Its reflective strips and soft lining add specific value for larger, high-profile vehicles where visibility and paint preservation are paramount. Ultimately, for a standard setup, the CAMMOO offers the more robust, all-weather defense I trust for long-term storage, especially when considering the needs of regular maintenance like for car washing, where the heavy-duty fabric holds up best.
Yes, the Xenjum RV Cover 35-38 includes high-visibility reflective strips on all four sides to enhance safety and prevent accidental collisions in the dark, a feature not listed for the CAMMOO model.
The Xenjum RV Cover 35-38 lists 6 airflow vents, whereas the CAMMOO RV Cover has 5, meaning the Xenjum option provides slightly more breathability for larger vehicles to reduce moisture buildup.
You should measure the longest points of your RV, including bumpers and spare tires. If you are between sizes, the Xenjum guide recommends choosing the larger size for a secure fit, while the CAMMOO is strictly sized for 24–27ft units.
