SL1422 RV Skylight Replacement 18 in x 26 in - Durable Smoke Dome

Our review of the SL1422 RV Skylight Replacement finds it best suited for RV owners who need a direct, heavy-duty replacement for a standard 14 in x 22 in opening. The single biggest reason to buy is its combination of a precise fit and thicker, impact-resistant polycarbonate that resists UV and high temperatures, which makes it an obvious choice for showers, bathrooms and living areas where light and weather protection matter. Installation accessories are included, so the product is ready for a straightforward swap that restores light and reduces glare.

Key Features

• Perfect Fit: Designed for 14 in x 22 in openings with an 18 in x 26 in outer cover so it aligns cleanly with standard RV cuts.
• Durable Construction: Thick, impact-resistant polycarbonate stands up to extreme weather and high temps for long-term reliability.
• UV Protection: Smoke tint reduces glare and filters UV, protecting interiors and improving comfort in bright conditions.
• Installation Ready: Comes with glue and self-tapping screws and pre-drilled holes to simplify fitting and reduce installation time.
• Large Flange: The wide roof flange helps resist wind and storms and provides space for sealant to prevent leaks.
• Light Control Options: Available in smoke gray to cut heat and glare while maintaining a natural view of sky and stars.

Who It's For

The SL1422 is ideal for RV, camper and trailer owners who need a direct replacement for an Icon SL1422D-Smoke or any unit that uses a standard 14 in x 22 in opening; it fits roofs that accept an 18 in x 26 in outer cover. It works especially well for people who want natural light in bathrooms and showers while reducing UV and heat transfer into the living space.

Those who should look elsewhere include owners seeking a built-in ventilation fan or integrated shade system, or users who require a crystal-clear, non-tinted cover for maximum daylight without any solar filtering. For custom or nonstandard roof cuts, measure carefully before ordering.

Pros & Cons
