XMK RV Skylight Replacement Bundle – Outer Dome 26x18 Fit for 14x22 Opening, Inner Dome 14x22, Sealant Included

Bright, Quiet, and Ready for Adventure

Upgrade your RV’s interior with the XMK RV Skylight Replacement Bundle. This dual-dome design traps air between the outer and inner domes, helping to reduce heat transfer and create a more comfortable living space without burning through energy. Built for standard 14" x 22" skylight openings, the bundle includes a robust outer dome (26" x 18" flange) and an inner dome (14" x 22" with a 16" x 23 7/8" flange), making it a versatile choice for RVs, campers, travel trailers, and even food trucks that rely on reliable natural light.

Beyond light, you’ll appreciate the practical details: thicker polycarbonate for durability, a UV-coated outer surface to slow sun damage, and a complete installation kit that helps reduce leaks and drafts. The kit is offered in three color options—smoke gray, white, and clear—each influencing light quality and heat filtration in different ways, so you can tailor the experience to your vehicle and climate.

What’s Included and How It Helps

• Inner and outer skylights designed to fit standard 14" x 22" openings, with a 4" ceiling thickness target for a solid seal.
• Outer dome with UV protection to preserve interior surfaces while inviting daylight.
• Inner dome paired with a precisely sized flange for a secure, tight fit.
• White self-leveling sealant for a leak-resistant, air-tight seal during and after installation.
• Pre-drilled mounting screws and clearly spaced features to simplify mounting and alignment.

Key Specs and Materials

• Outer dome: 14" x 22" with a 4" depth; flange: 26" x 18"
• Inner dome: 14" x 22" with a 4" depth; flange: 16" x 23 7/8"
• Thicker polycarbonate construction for enhanced impact resistance and longevity in outdoor conditions
• Anti-UV coating on the outer dome to reduce sun exposure to RV interiors

Color Options and Use Cases

• Smoke gray reduces harsh heat and UV while still letting in daylight for a balanced interior glow.
• White increases the amount of natural light entering the RV for a brighter cabin feel.
• Clear maximizes daylight transmission for a truly open, airy space during travel and camping.

Installation and Practical Tips

The bundle was designed with user-friendly installation in mind. Expect a straightforward mounting process with pre-drilled holes and a sealant tube that helps you create a watertight seal. A well-sealed skylight can contribute to steady interior temperatures and fewer drafts as you move between shaded and sunny spots.

While results can vary by RV model and climate, many customers find that a dual-dome setup helps maintain comfortable temperatures and preserves interior finishes from sun exposure. Consider your climate, preferred lighting, and heat management goals when choosing between the three color options.
