RVGUARD RV Skylight Inner Dome
The RVGUARD inner dome is designed for standard 14″ x 22″ skylight openings, making it a straightforward replacement for many RV models. It features a universal fit for wall thicknesses around 70mm and above, a high light transmittance of up to 88%, and a durable ABS plastic body with a PC clear window. This combination aims to brighten interiors while withstanding weather. Best for full-time travelers needing a reliable bright interior and a durable, heat-resilient dome.
Best for: RV owners who want a bright, clear interior with a simple install. Avoid if your wall thickness is significantly thinner than 70mm or if you require enhanced insulation beyond light transmission.
EDIETH 14x14x3 Insulator Cover
EDIETH offers a universal reflective insulator designed for 14×14 RV skylights and vents, including some slightly larger openings. It uses a durable aluminum-coated surface to reflect up to 98% of sunlight, paired with a thick memory foam layer to reduce heat transfer and drafts. It’s a strong choice for campers seeking seasonal insulation and noise reduction, particularly when sitting in hot sun or cold conditions.
Best for: RV owners who want reliable thermal insulation and noise reduction for 14×14 skylights. Choose this if you need a snug draft-free fit and improved comfort across seasons.
ALP Lighting 11in White Round Acrylic Drum Style Cover

RVINGPRO Magnetic RV Skylight Shade
The RVINGPRO skylight shade is a dual-sided blackout option designed for RV vents.

The oxford fabric side blocks light effectively, while the reflective layer helps deflect UV rays. Best for: travelers who need adjustable light control and easy removal when not in use. Caution: not a replacement for the interior dome itself; it is a shade accessory.
NEW SKYLIGHT Inner Dome 14″ X 22″
This is a dedicated interior dome replacement for 14″ x 22″ skylights. It serves as the inner garnish, designed to accompany a standard 14×22 exterior dome (item #777104692). It’s intended for use with a ceiling thickness of about 3 inches, making it a suitable match for many RV skylight assemblies. Best for: owners replacing the inner dome while maintaining a compatible exterior dome. Limitation: ensure the outer dome and mounting thickness align with your current system.
GEATaaT RV Skylight Outer Dome
While this product is an outer dome, it’s designed to fit standard 14″ x 22″ skylight openings and provides UV protection with a polycarbonate body. It’s a practical option for replacing the external dome when the interior components remain intact. Best for: RV owners who need a full exterior dome replacement and enhanced weather resistance. Limitation: not an interior dome replacement; ensure compatibility with your existing inner dome.
Buying Guide
- What size do I need? Ensure the dome or cover matches a 14″ x 22″ opening for most standard RV skylights. Some inner domes fit 14×22 openings with a specific thickness requirement.
- Which material matters? ABS with a PC window offers impact resistance and brightness. Aluminum-coated insulators provide thermal reflectivity. Polycarbonate outer domes add UV protection and weather durability.
- Is insulation important? If you camp in varied climates, consider insulators or reflective covers that reduce heat transfer and drafts.
- Do I need a shade or a dome? Shades control light; domes affect brightness and sealing. For light control, combine a shade like RVINGPRO with a compatible inner dome for best results.
- What about universal fit? Look for universal size options if your RV model varies or you frequently replace the opening.
