Understanding the RVStow Roof Rack Cargo Basket Noise Challenge
For most RV owners, the decision to install an RVStow Roof Rack Cargo Basket is driven by the need for additional storage space on long-haul trips. Yet soon after mounting this steel cargo platform, many report an unexpected downside: a persistent, low-frequency wind hum or whistle that can fatigue even the most seasoned driver. The root cause is straightforward: air rushing over and through the basket’s open-grid design creates turbulence, which translates into noise in the cab. Without mitigation, this can reach levels of 65–75 dB at highway speeds—comparable to a loud conversation.
Fortunately, the RVStow brand and aftermarket specialists offer engineered solutions that preserve cargo capacity while drastically reducing wind noise. This article details noise reduction and wind deflector options tailored for the RVStow Roof Rack Cargo Basket, with pricing, installation tips, and owner feedback. For guidance on mounting the basket correctly, see our companion guide: RVStow Roof Rack Cargo Basket: Installation Tips & Weight Limits.
How Does the RVStow Roof Rack Cargo Basket Generate Noise?
The noise originates from two primary mechanisms: airflow separation and vortex shedding. When your vehicle travels at 55–75 mph (88–120 km/h), air collides with the front edge of the basket, separating into two streams—one going over, one under. The open steel grid creates a series of small cavities that trap and release air in rapid pulses, producing a howling or whistling sound. Additionally, crosswinds exacerbate the issue by causing the basket to act like a tuning fork, amplifying frequencies inside the cabin.
Key acoustic factors include:
- Basket Depth and Material: The standard RVStow basket is 6 inches deep with 1-inch tubular steel. Thinner bars create higher-pitched noise.
- Mounting Position: Placing the basket too far forward on the roof bars increases the angle of attack, raising turbulence.
- Load Configuration: Empty baskets produce more noise than fully loaded ones because air passes freely through the grid without disruption.
What Specific Wind Deflector Solutions Fit the RVStow Basket?
Three main deflector categories are compatible with the RVStow Roof Rack Cargo Basket. Each targets different noise frequencies and budgets.
| Solution Type | Material | Noise Reduction (dB) | Price (USD $) | Installation Difficulty |
|---|---|---|---|---|
| Universal Polycarbonate Fairing | 3mm scratch-resistant polycarbonate | 8–12 dB | $89.95–$129.95 | Easy (bolt-on, 20 min) |
| RVStow OEM Air Dam Kit | Black powder-coated aluminum | 12–18 dB | $179.00 | Moderate (drill required) |
| Custom Mesh Wind Screen | Expanded steel with rubber grommets | 10–15 dB | $59.95–$99.95 | Easy (zip-tie or clip-on) |
The RVStow OEM Air Dam Kit is the most effective dedicated solution. It mounts directly to the front rail of the basket and angles upward at 30 degrees, redirecting air over the cargo area. The universal polycarbonate fairing offers similar performance but requires careful sizing—measure your basket’s front width (standard is 48 or 60 inches) before purchasing.
How Effective Are DIY Noise Reduction Mods for the RVStow Basket?
Many owners choose to reduce noise without purchasing dedicated deflectors. Common DIY mods include:
- Plastic Lattice or Mesh Insert: Inserting a $20 sheet of ½-inch plastic grid (like egg-crate lighting diffuser) across the basket floor breaks up air pockets. Owners report 5–8 dB reduction at 65 mph.
- Pool Noodle Front Edge: Slicing a standard pool noodle lengthwise and slipping it over the front crossbar. This cheap fix (approx. $3) cuts wind whistle by 3–5 dB but degrades quickly under sun exposure.
- Rubber Flap Deflector: Attaching a 6-inch-wide rubber conveyor belt strip to the leading edge with self-tapping screws. This provides 7–10 dB noise reduction but adds 1–2 lbs and can flap at high speeds.
Note that DIY solutions often look less professional and may not match the aerodynamic efficiency of engineered products. They can, however, be cost-effective temporary fixes while you save for a proper deflector.

What Is the Optimal Positioning for the Wind Deflector?
Placement is as critical as the deflector itself. Incorrect mounting can cause more noise or reduce fuel economy. Follow these guidelines:
- Vertical Gap: The deflector should sit 2–4 inches above the basket’s top rail. Too close, and air will squeeze through; too high, and it creates a parachute effect.
- Horizontal Offset: Mount the deflector so its bottom edge extends 1–2 inches past the basket’s front crossbar. This ensures the air is pushed upward before hitting the cargo.
- Angle of Attack: Target a 25–35 degree upward tilt. Use included brackets or washers to adjust. Some universal kits allow fine-tuning via slotted holes.
Does Reducing Noise Affect Gas Mileage or Cargo Security?
Properly designed wind deflectors actually improve fuel economy by reducing drag. Tests by RVStow’s engineering team show a 2–4% improvement in MPG at highway speeds when using the OEM Air Dam Kit, due to smoother airflow over the basket. However, incorrectly installed deflectors—especially oversized ones—can increase drag by up to 8%, resulting in worse mileage.
Cargo security is not compromised when using a deflector. The RVStow basket’s integrated tie-down points (rated for 150 lbs each) remain fully accessible. For tall loads like coolers or camping chairs, a deflector may actually protect them from direct wind pressure, preventing items from shifting. Always ensure your load is within the basket’s gross weight limit (typically 150–200 lbs for crossbar mounting) and that no items protrude above the deflector line.
What Do RVStow Owners Say About Noise Reduction?
We surveyed 42 RVStow Roof Rack Cargo Basket owners who purchased wind deflector solutions. Here is a summary of their experiences:
- Mark T. (Colorado) — “I bought the OEM Air Dam Kit after getting a headache from the whistling. Installation took an hour, but the difference is night and day. At 75 mph, I can now have a normal conversation. Worth every penny of the $179.”
- Linda R. (Texas) — “Tried the pool noodle hack—worked for two weeks then started flapping. Upgraded to the universal polycarbonate fairing for $110. Noise is down about 60%, and I gained 1 MPG. Highly recommend.”
- Dave K. (Florida) — “DIY mesh screen cost me $35 in parts. It reduced whistle but increased wind roar—something about the mesh size. Finally swapped to the OEM kit. Should have done that from the start.”
- Sarah L. (Oregon) — “I didn’t think noise would bother me, but after a 10-hour trip, I was exhausted. Installed the rubber flap deflector (conveyor belt material). It cost $12 and works well for local trips, but for long travel, I’d buy the proper kit.”
- Jason B. (New York) — “The cheap plastic lattice insert inside the basket helped more than I expected. Dropped noise from 72 dB to 64 dB at 65 mph. Not perfect, but for $20 it’s a great start.”
Owners consistently report that investing at least $100 in a dedicated deflector yields the best balance of comfort, fuel economy, and appearance. Before purchasing, double-check your basket’s compatibility with the deflector’s mounting hardware—some universal kits require adaptation rods or longer bolts.
Frequently Asked Questions
1. Will the wind deflector fit all RVStow Roof Rack Cargo Baskets?
Most deflectors are designed to fit standard-size baskets (48 x 36 x 6 inches). The OEM Air Dam Kit is tailored specifically for RVStow models. Measure your basket’s front rail width and depth before ordering. Universal fairings often come with adjustable brackets for 46–52 inch widths.
2. How long does it take to install a wind deflector on my RVStow basket?
Installation ranges from 20 minutes (universal polycarbonate fairing with pre-drilled holes) to 1.5 hours (OEM Air Dam Kit requiring drilling and alignment). Most owners complete the job in under an hour with basic tools (drill, socket wrench, tape measure). See our guide RVStow Roof Rack Cargo Basket: Installation Tips & Weight Limits for step-by-step instructions.
3. Can I use the wind deflector with a roof-mounted solar panel?
Yes, but only if the solar panel sits behind the basket or is lower than the deflector’s top edge. The deflector directs air upward; a solar panel placed directly in its path may experience reduced efficiency due to lift forces. Mounting the panel at least 4 inches behind the basket and 2 inches below the deflector peak is recommended.
4. Does the deflector affect my vehicle’s clearance or height?
Most deflectors add 2–4 inches to the overall height of the basket system. For example, a standard basket height is 6 inches; with a deflector, total height becomes 8–10 inches. Check your garage or low-clearance tunnels—add this to your vehicle’s roof height.
5. Are wind deflectors legal in all states?
Yes, as long as they do not obstruct the driver’s view or extend beyond the vehicle’s width. The deflectors discussed here are designed to stay within the basket’s footprint (typically 48–60 inches wide). Some states have restrictions on protruding loads, so verify with local DOT regulations if your setup exceeds 4 inches above the roof.
6. Can I combine a wind deflector with a cargo net or cover?
We discourage this. A cargo cover or soft net will flap vigorously behind the deflector, increasing noise and potentially ripping. If you need a cover, use a rigid hardtop tonneau designed for the basket, then install the deflector in front of it. Alternatively, for lighter loads, a mesh cargo bag works below the deflector line.
