HECASA 18in x 26in RV Skylight Cover for 14in x 22in Dome - Clear

In this review the HECASA 18in x 26in RV Skylight Cover is evaluated for RV owners who need a clear replacement for a 14in x 22in dome opening. The bottom line: it is a straightforward, low-cost way to restore daylight and weather protection to an older camper roof window, and its clear finish lets in natural light while keeping out rain and debris. The review focuses on fit, material durability and practical installation notes so buyers know what to expect before drilling and screwing this cover into place.

Key Features

• Universal fit: Designed to cover a 14in x 22in dome opening with an 18in x 26in flange so it works on many travel trailers, campers and trucks when measurements match.
• Thick material: Molded from lightweight, high-hardness plastic that resists impact and wear for everyday road use.
• Weather resistance: Built to withstand hot and cold weather without rapid fading, keeping the RV interior dry and protected from the elements.
• Light transmission: The clear skylight design provides natural daylight to the living space, improving cabin comfort during the day and view of the night sky.
• Simple replacement: Supplied as the cover only so users can replace a cracked or missing dome quickly using screws and existing flange holes.

Who It's For

This skylight cover is best for DIY RV owners and technicians who already know the exact dome and flange sizes on their roof window and who want a clear replacement that restores light and basic weather protection. It suits travel trailers, pop-up campers and trucks with a 14in x 22in dome and an 18in x 26in flange footprint.

Buyers who should look elsewhere include those who need a complete installation kit with hardware or detailed instructions, and owners seeking a factory-matched custom dome for an unusual roof profile. Also consider alternatives if you need heavy UV filtering or a guaranteed multi-year crack resistance under extreme winter conditions.

Pros & Cons

Cons
