MaxxAir II Vent Cover — Black (00-933082)
Published · Researched 2026-09-21
2026 lineup note: Current and unchanged. The MaxxAir II in black (part 00-933082) is MaxxAir's arched, louvered cover for standard 14 × 14 in RV roof vents — rain protection with the vent open, zero roof penetrations. Siblings: white (00-933081) and smoke (00-933083). Street price ~$39–66 USD (Sept 2026).
Version lineage (2023–2026)
- Pre-2023: MaxxAir (original) — the flat-top cover with the "MAXXAIR" logo; part 147-25 in black. Still sold and still common — the main source of shopping confusion.
- 2023–2026: MaxxAir II (current) — redesigned arched shell with rear louvers, "MAXXAIR II" logo, hinged snap-pin access for cleaning without tools, high-density polyethylene. Black = 00-933082, white = 00-933081, smoke = 00-933083. No hardware or design revision in the captured window — the II is a mature, static product.
- Accessory: bug screen 00-955202 (sold separately); Fanmate covers are a different MaxxAir line for powered fans — not interchangeable.
Overview
The MaxxAir II is the default answer to "how do I leave the roof vent open in the rain": a black HDPE shell that mounts to the existing 14 × 14 in vent flange with four aluminum brackets — no new roof holes, no sealant. The arched profile and rear louvers vent hot air while shedding rain; the hinged design with snap pins lets you open it for vent cleaning without removing hardware. It does not include a bug screen, and on some vent/fan combos the fan lid can't fully open under the cover — check your vent model before ordering.

In the Box
MaxxAir II black cover (00-933082), 4 aluminum mounting brackets, installation hardware, instructions. Bug screen and vent/fan unit sold separately.
Warranty
6-year limited manufacturer warranty — MaxxAir (Airxcel). Covers defects in materials/workmanship; UV degradation beyond normal weathering and impact damage excluded. Keep the receipt — warranty follows proof of purchase.
Support & Parts
MaxxAir/Airxcel supports the line with replacement brackets, snap pins, and bug screens (00-955202) sold as parts. The cover is a single molded shell — if it cracks outside warranty, replacement is the fix. Decades-long product support; the original MaxxAir is still supported.
Community Verdict
The MaxxAir II is the forum-default vent cover — My Grand RV threads recommend it over generics for fit and the tool-free cleaning access, and owners like leaving vents open in rain and while driving (with the vent open under the cover). Complaints are fit-specific, not quality: powered vent fans whose lids hit the cover, and low-clearance roofs. The white-vs-black debate is aesthetic and thermal (black looks better on dark roofs; white stays cooler). Generics exist cheaper, but the bracket fit and 6-year warranty keep the II the recommendation. No fabricated scores.

Research date: 2026-09-21. Specs cross-verified across MaxxAir dealer listings (Dyers, RVUpgradeStore answers, Tweetys) and forum install threads. Two wrong-variant images (original MaxxAir "I" black) were rejected during visual verification. Re-verify live: street price and bug-screen part availability.
Long-term durability & warranty-claim reality (enrichment — Sept 2026)
HDPE vent covers live the hardest life in RVing — full sun, hail, highway wind — and the MaxxAir II's reputation is that it survives it: decade-old MaxxAirs (I and II) are common on used rigs, usually just faded. The failure modes are UV chalking/fading (cosmetic, years 5+), bracket hardware loosening from vibration (re-torque annually), and impact cracks from hail or low branches. The 6-year warranty is generous for a $50 plastic part and MaxxAir honors it for genuine defects — but UV fade is weathering, not a defect, so don't expect a free cover in year 5 because it's chalky. Black shows chalking more than white; 303-type UV protectant is the standard owner practice.
Version history — year by year (enrichment — Sept 2026)
- 2023: MaxxAir II current in all three colors; original MaxxAir still sold alongside.
- 2024: Continued unchanged.
- 2025: Continued unchanged.
- 2026: Continued unchanged at ~$39–66 street; no redesign announced as of Sept 2026. The II remains the current generation.
Head-to-head vs closest rivals (enrichment — Sept 2026)
No vent-cover dossiers exist in the catalog yet — the comparisons below are conceptual, against the products owners actually cross-shop. No catalog links are fabricated for them.
- vs MaxxAir (original, "I"): the predecessor — flatter top, "MAXXAIR" logo, part 147-25 in black. Still sold, often cheaper. The II's arched shell vents better and the hinged snap-pin cleaning access is the real upgrade; the I is fine if you find it significantly cheaper and don't care about tool-free access.
- vs MaxxAir Fanmate: MaxxAir's cover line for powered roof fans (e.g., over a MaxxFan) — different product, different fit. Don't buy a Fanmate for a plain vent or a II for a powered fan; check the application chart.
- vs generic vent covers: Amazon generics run $20–35 — thinner plastic, fussier brackets, 1-year-ish warranties. The II's 6-year warranty and exact 14×14 fit are what you're paying for.
Care & maintenance (enrichment — Sept 2026)
Wash with mild soap; avoid petroleum solvents on HDPE. Annually re-torque the four bracket bolts (vibration loosens them) and inspect the roof sealant around the vent flange while you're up there — the cover install is the natural reminder. Snap pins: a dab of silicone lubricant keeps the hinge action smooth. UV protectant (303 Aerospace or similar) slows chalking, especially on black. Open via the hinge pins to clean leaves/debris from under the cover each spring.
Buying traps (enrichment — Sept 2026)
- MaxxAir I vs II: listings mix them freely — the I has the flat top and "MAXXAIR" logo; the II has the arched shell, rear louvers, and "MAXXAIR II" logo. Confirm part 00-933082 for black II. (Two wrong-variant "I" images were caught and rejected during this research — sellers make the same mistake.)
- Color codes: 00-933081 = white, 00-933082 = black, 00-933083 = smoke. A "smoke" cover photographed in bright light can pass for black in thumbnails.
- Fan-lid clearance: if you have a powered vent/fan, verify the lid opens fully under the cover — some combos don't, and that's a return.
- Bug screen not included: part 00-955202 is separate; factor it in if your vent lacks a screen.
- Mount rear-facing: the louvers face the rear of the RV — installing backwards is the classic DIY error and kills the rain-shedding.
Community Verdict — additional voices (enrichment — Sept 2026)
Additional sourced voices (Sept 2026): My Grand RV roof-vent-cover thread — MaxxAir recommended over generics for bracket fit; install-tips thread — rear-facing mount, check sealant while up there, snap-pin cleaning praised; RVUpgradeStore answers — bug screen confirmed as separate part 00-955202, vent can stay open while driving under the cover. No fabricated scores.
