XMK RV Skylight Replacement Bundle 14" x 22" Fit — 18"x26" Outer + 16"x23.875" Inner Dual-Dome, UV-Coated White Sealant

XMK's RV Skylight Replacement Bundle is a complete two-piece skylight set (outer 18"x26" flange, inner 16"x23 7/8" flange) with a 14"x22" dome pair and polyurethane sealant, designed to replace standard 14"x22" RV openings.

Replacing a faded or cracked skylight can restore daylight, reduce drafts, and help protect an RV interior. This XMK bundle includes both outer and inner domes made from reinforced polycarbonate, a tube of white self-leveling lap sealant, and mounting hardware, so you can swap out the old components in one job. The double-dome design traps an insulating air gap between the inner and outer pieces to reduce heat transfer and add durability in varied weather conditions.

How does this skylight improve light and temperature inside my camper?

The two-piece construction lets natural light in while creating an insulating air space that moderates heat gain and loss. Outer domes are UV-coated to protect the cabin and inner domes diffuse light for a softer interior glow. Choosing between smoke gray, white, or clear lets you balance brightness and solar filtering.

• Double-dome design traps air for passive insulation.
• UV-coated outer dome reduces fading from sunlight.
• Color options: smoke gray (heat filter), white (softer light), clear (maximum light).

Will this fit my RV's 14" x 22" roof opening and how is it measured?

This replacement fits standard 14" x 22" skylight openings where the ceiling thickness is greater than 4 inches. The outer dome has a flange dimension of 18" x 26" to sit on the roof surface; the inner dome flange measures 16" x 23 7/8" to finish neatly on the interior ceiling. Verify your current skylight opening and ceiling thickness before installing.

• Fits standard openings: 14" x 22" (verify exact cutout).
• Outer flange: 18" x 26"; inner flange: 16" x 23 7/8".
• Designed for ceiling thickness greater than 4".

What materials and hardware are included, and how durable is the kit?

Both domes are made from thicker, impact-resistant polycarbonate engineered for outdoor use and coated on the outer surface to block UV exposure. The bundle arrives with pre-drilled mounting holes, supplied screws, and a tube of white polyurethane self-leveling lap sealant to create a watertight bond. The robust construction stands up to road vibration, weather, and everyday wear in RV, camper, travel trailer, or food truck applications.

• Reinforced polycarbonate inner and outer domes for strength.
• Anti-UV coating on the outer dome to protect interiors.
• Includes screws, pre-drilled holes, and a tube of white sealant.

How difficult is installation and what tools are recommended?

Installation is a straightforward roof-to-ceiling replacement for someone comfortable with basic RV repairs. Pre-drilled mounting holes speed alignment while the included sealant levels itself to help stop leaks; you will still need common hand tools and a sealant gun. If your original skylight used a fan or shade assembly, remove those components first and confirm wiring or attachments won't be affected.

• Requires basic tools: screwdriver/drill, caulking gun, utility knife.
• Pre-drilled holes and supplied screws simplify mounting.
• Sealant provided for watertight installation; allow cure time per instructions.

Who is this for: The XMK RV Skylight Replacement Bundle is intended for RV owners, camper renovators, and mobile-business operators who need a full skylight swap for standard 14" x 22" openings. It suits anyone looking to restore daylight, improve interior comfort, and secure a weather-resistant skylight using thicker polycarbonate domes and included sealing hardware. Always measure your opening and review mounting requirements before ordering to ensure compatibility.
