The XMK skylight replacement covers a 18″ x 26″ outer dome with a 14″ x 22″ opening. It is designed to fit standard RV skylight openings across RVs, campers, travel trailers, motorhomes, and fifth wheels. The roof flange provides a substantial surface to withstand wind and storms.

The product emphasizes outdoor durability and a bright interior when daylight enters the RV’s shower, bathroom, and living spaces.
RV Skylight Replacement Bundle Outer And Inner Dome
This bundle includes both inner and outer skylight domes compatible with 14″ x 22″ openings. Outer dome flange dimensions are 26″ x 18″ and inner dome dimensions are 14″ x 22″ with compatible flange sizes. The set is designed to trap air between domes to reduce heat transfer and maintain a comfortable interior climate. Both domes are constructed from thicker polycarbonate for enhanced impact resistance and weather durability. An anti-UV coating on the outer dome helps protect RV interiors from sun damage.

HECASA offers an 18″ x 26″ outer skylight dome designed to fit 14″ x 22″ shower roof openings in camper, food truck, and motorhome configurations. The white exterior is paired with polycarbonate construction for durability against impact and weather exposure. This replacement cover is meant to enhance natural light while providing protective shielding from wind-driven rain and UV rays, contributing to improved interior comfort and energy efficiency.
XMK RV Skylight Replacement Inner Dome
The XMK inner dome is designed for 14″ x 22″ skylight openings and includes screws for installation. The inner dome allows light to enter while preserving interior climate when paired with an outer cover. Its 2.9″ height profile and clear window design help maximize daylight transmission. The product is suitable for RV showers, living areas, and other interior spaces that rely on skylight illumination, especially when paired with an outer dome.
Universal 14″ RV Roof Vent Cover Kit
This universal vent cover kit provides a vent lid option for 14″ x 14″ openings and is compatible with many trailers, campers, and motorhomes. While not a skylight dome, it complements dome coverage by offering an additional protection layer for roof vents. The kit emphasizes durable vent lids and weather sealing, helping prevent water intrusion and reduce heat gain around vent openings. It’s a practical addition for those seeking a comprehensive roof protection solution.
Buying Guide
- Fit and dimensions: Ensure the outer dome measures 18″ x 26″ and the opening is 14″ x 22″ to match common RV skylights. Some bundles include inner domes with matching openings for improved insulation.
- Material and durability: Look for thick polycarbonate with UV coatings. This combination provides impact resistance and reduces interior fading from sun exposure.
- Thermal management: Dual-dome designs or air-trap configurations help reduce heat transfer, keeping interior temperatures more stable and potentially lowering energy use.
- Weather resistance: Check for wind, rain, and storm resistance. A wide flange and robust sealing improve roof integrity during severe weather.
- Ease of installation: Consider whether the kit includes screws, gaskets, and clear installation instructions. Compatibility with existing skylight openings simplifies replacement.
- UV protection: UV coatings protect interior fabrics and furniture from sun damage, extending the life of RV interiors.
- Combination options: Bundles offering both inner and outer domes provide better insulation and light control, but require careful handling during installation.
- Maintenance: Select domes that are easy to clean with clear visibility and minimal clouding over time. UV coatings should resist yellowing.
- Installation environment: If you frequently travel to high-wind areas, prioritize domes with reinforced edges and wide flanges for secure mounting.
- Warranty and support: Check manufacturer warranties and available replacement parts for long-term serviceability.
When upgrading your RV skylight dome covers, evaluate how the product will influence daylight, interior comfort, and energy use. A durable outer dome with UV protection reduces interior fading, while an inner dome can improve insulation and reduce heat exchange. Consider whether you prefer a single outer dome or a dual-dome configuration for maximum climate control. Finally, verify compatibility with your RV’s roof structure and skylight opening to ensure a proper seal and straightforward installation.
