This skylight replacement by XMK is a direct-fit outer dome designed to cover standard 22"×22" roof openings while the larger 26"×26" flange provides a secure mounting surface. Molded from thick polycarbonate, the dome balances strength and light transmission so you get more daylight inside your camper without sacrificing durability. It's prepped for straightforward installation and comes in multiple sizes and finishes to suit different rigs and personal preferences.

Will this skylight actually fit my RV's 22"×22" opening?

Yes — the dome's main body measures 22"×22" with a surrounding 26"×26" flange that sits on the roof. The oversized flange gives installers extra surface area to fasten and seal the dome securely.

• Inner dome: 22"×22" footprint to match common factory openings
• Outer flange: 26"×26" for stable mounting and sealing
• Pre-drilled hole layout to guide attachment locations
• Lightweight material reduces strain during handling

How durable and weather-resistant is the XMK replacement dome?

The XMK dome is molded from high-grade polycarbonate that resists impact and tolerates temperature swings better than ordinary acrylic. A UV-rated surface coating minimizes solar degradation and helps protect the RV interior from harmful rays.

• Polycarbonate construction for improved impact resistance
• UV protective coating to slow yellowing and fading
• Engineered for outdoor use in varied climates
• Thicker profile than thinner aftermarket domes for longer life

How much light and heat control should I expect from the smoke-gray option?

Smoke-gray tints reduce glare and filter summer heat while still admitting ample daylight to make interiors feel open. Compared with clear domes, the smoke finish cuts direct sun intensity but preserves natural illumination, useful for bathrooms, showers, and living spaces.

• Filters harsh sunlight to lower interior brightness peaks
• Helps reduce perceived heat from direct sun exposure
• Maintains a view of sky and stars without over-brightness
• Available alongside clear, white, dark blue, tawny, and black options

What is required to install the skylight and avoid leaks?

Installation is straightforward for someone comfortable with basic roof work: align the dome, fasten through the flange using the pre-marked holes, and apply a quality skylight sealant around the flange perimeter. Because the dome is lighter than glass, it’s easier to lift and position safely.

• Use appropriate screws or fasteners for your roof material
• Apply a compatible roof/skylight sealant to prevent leaks
• Drill/trim holes as needed — pre-drilled guides are provided
• Consider a helper for positioning the dome during attachment

Who this is for: The XMK 26"×26" outer dome is aimed at RV owners, campers, and vanlifers who need a rugged, easy-to-install skylight replacement for a standard 22"×22" opening. It suits those who want to brighten interiors with natural light while improving impact resistance and UV defense. Choose smoke-gray if you prefer moderated brightness and reduced solar glare, or pick another finish to match your desired light level and aesthetic.
