RecPro Inner Garnish for Rectangular Skylight

The RecPro inner garnish is a lightweight acrylic trim ring designed to cover the sides and inner edges around a skylight hole. It delivers a sleek, finished look while shielding edges from moisture and wear. Made from acrylic plastic, the garnish resists chemicals, high temperatures, and impacts, helping your skylight area stay visually appealing over time. Available in 14″ x 14″ and 14″ x 22″ options, it offers straightforward installation, though hardware and tools are not included in the package.
Key considerations: fit must match your skylight dimensions, and ensure that your installation surface is clean and even. Since this option is acrylic, it presents a crisp, modern aesthetic that complements most RV interior styles. While it is easy to install, buyers should plan for basic tools and a clean workspace to achieve a tight finish and prevent gaps where moisture might collect.
HECASA Skylight Replacement for 14×22 Openings

The HECASA skylight replacement is designed for versatility, fitting 18″ x 26″ outer dimensions and accommodating standard 14″ x 22″ roof openings. Cast from polycarbonate, the panel emphasizes hardness and impact resistance, with a robust roof flange to withstand winds and storms. Light transmission is managed to filter glare while preserving natural brightness, with options for smoke or clear finishes to tailor brightness and privacy. This product is suitable for RVs, campers, travel trailers, and motorhomes seeking a balance of durability and light control.
Considerations include confirming your sunroof size before purchase and evaluating climate needs. For areas with strong sun or frequent weather exposure, the polycarbonate construction offers reliable durability. Potential buyers should assess whether they need additional insulation or blackout features to optimize comfort, particularly in bathrooms or living spaces where privacy and light control matter.
ZOIZ 14×14 RV Vent Garnish with 2.9″ Leg

The ZOIZ interior trim ring is a modular solution for 14″ x 14″ skylight vents, featuring a 2.9″ vertical leg depth for secure mounting.

It is positioned as a straightforward upgrade for RVs that want a clean, cohesive look around roof vent openings. The product is compatible with a variety of 14×14 skylight configurations and emphasizes an easy, tool-light installation process.
Practical considerations include confirming the depth of your vent opening and ensuring that the ABS trim aligns with the outer skylight housing for a seamless seal. This option is especially appealing for owners seeking a budget-friendly, durable trim that maintains a fresh interior appearance without extensive remodeling.
ADKUN 25 ft Vinyl Trim Molding Insert

It is versatile for multiple applications, including wall edges, door panels, and even some interior trim, allowing it to serve as a universal adhesive-free solution for a polished look around skylight installations and beyond.
Key considerations include length coverage and whether the molding will need heat-forming or bending for irregular routes. This option is particularly suitable for owners who want a long roll of trim that can be repurposed across various parts of the RV, not just skylights. It may require careful measurement to prevent over-length trimming during installation.
RV Designer 1 Inch Vinyl Trim Insert

The RV Designer vinyl trim insert offers durable, flexible molding ideal for exterior and interior RV applications. The 1-inch wide trim is designed for roof trim, corners, and screw cover improvements, supporting a cleaner, more finished look. It is marketed as a heavy-duty option, with easy installation that can quickly upgrade the visual appeal of travel trailers and campers. This trim can be used to cover seams or edges while resisting the elements during excursions.
When evaluating this option, consider the compatibility with your existing skylight trim and whether you need more rigidity or some flexible adaptation for rounded surfaces. For owners seeking a long-lasting, versatile molding solution, this vinyl insert provides a balanced combination of durability and ease of use.
classAcustoms 18×26 Skylight with Tinted Glass (Smoke)

This exterior skylight upgrade features an 18 x 26 OD/14 x 22 ID smoked tint, offering privacy along with UV protection. The option is designed for easy mounting, with pre-drilled mounting flange dimensions for straightforward attachment. The tinted finish helps reduce glare and interior heat gain while preserving a stylish look for RV roofs and skylights. The construction emphasizes durability and a premium appearance, suitable for travelers who want a premium, darker-tinted skylight finish.
Purchase considerations include whether you prefer a smoky tint for privacy and light control versus a clear finish for maximum brightness. This option suits RV owners prioritizing strong exterior aesthetics and durable mounting hardware that simplifies installation and long-term performance.
funomo RV Skylight Window Shade

The Funomo skylight window shade offers a 23.25″ x 15.25″ rectangular shade designed for universal fit across many RV skylights. The three-layer construction delivers full light blackout for privacy while still allowing airflow when opened for ventilation. Its magnetic collapsible design and hook-and-loop fasteners provide flexible adjustment for different skylight configurations, enabling customized blackout heights. This shade helps balance energy efficiency and interior comfort in hot or bright environments.
When choosing this option, verify that the dimensions align with your skylight opening, as the product notes a universal fit rather than a guaranteed match for every model. The shade is particularly beneficial for campers seeking strong privacy without installing permanent fixtures, and its foldable design supports easy storage during travel.
Buying Guide: Key Purchase Considerations for RV Skylight Trim and Accessories
- Skylight size and opening: Confirm exact exterior and interior dimensions before buying trim or shades. Some products list outer dimensions, while others specify inner openings. Measure length, width, and depth to ensure proper fit.
- Material and durability: Acrylic, polycarbonate, ABS, and vinyl each offer different levels of impact resistance, UV stability, and temperature tolerance. Choose based on climate, exposure to sunlight, and potential for hail or wind.
- Light control and privacy: Decide whether you want full blackout, glare reduction, or natural light with privacy. Tinted skylights and multi-layer shades provide varying privacy and brightness levels.
- Installation effort: Some trim rings require tools and basic carpentry, while others are tool-free or self-adhesive. Consider your DIY comfort level and whether you want a temporary or permanent solution.
- Protection against moisture: Proper seals and trims help prevent water intrusion. Look for products designed to seal around skylight openings and resist cracking, yellowing, or warping over time.
- Versatility and compatibility: If you own multiple RVs or plan future upgrades, adjustable trim molding or universal shades may offer more value. Check length options and whether parts can be repurposed for other openings.
- Finish and aesthetics: Consider interior color schemes and the overall look you want. Clear, smoked, or white trims provide different visual effects and can complement aluminum or wood interior styles.
These options collectively cover a broad range of preferences—from ultra-durable polycarbonate skylights with glare control to flexible vinyl trims for DIY enthusiasts. When selecting, document your exact skylight opening, climate conditions, and installation goals to optimize both function and appearance on the RV.
