Why You Should Trust Me
As an auto mechanic and truck enthusiast, I’ve been installing tonneau covers for over 15 years. After owning trucks from Ford, Chevy, GMC, and Toyota, I’ve learned first-hand how important it is to find the right cover.
The wrong cover can cost you hundreds extra in gas every year or leave your cargo exposed to thieves and weather. After evaluating dozens of the most popular covers on the market, I’ve narrowed down the best options for durability, protection, ease of use, and aerodynamics.
My tonneau cover recommendations come from both extensive product research and real-world long-term testing. I put each cover through the wringer to provide reliable recommendations you can trust. If aerodynamics and gas savings are important to you, I’m confident one of these covers will exceed your expectations.
Who Should Consider an Aerodynamic Tonneau Cover?
There are a few major benefits that make aerodynamic tonneau covers worthwhile investments:
- Improved Gas Mileage – Reducing wind drag and turbulence in your bed can increase MPG by 10% or more at highway speeds. For the frequent long-haul driver, that can mean significant fuel cost savings each year.
- Added Cargo Protection – Keeping your gear locked safely under a hard or vinyl cover protects it from weather, UV rays, and thieves looking to steal a quick unattended item.
- Enhanced Style – Tonneau covers give your truck a sleek, finished look compared to an open bed. Higher profile toppers can make trucks seem bulky.
- Greater Cargo Versatility – Hinged and folding covers allow you to quickly access a portion or all of your bed for large items. You don’t have to fully remove the cover.
For anyone who drives their truck daily on the highway, keeping gear secure, or wants to enhance the overall aesthetics, an aerodynamic tonneau cover is a great investment.
How to Choose the Best Aerodynamic Tonneau Cover?
With so many types and options to consider, it can be tricky deciding which tonneau best fits your needs. Here are some key factors to keep in mind:
- Cover Type – Hard folding, soft roll-up, and retractable covers generally provide the best aerodynamic shape. Snap, hinged, and toolbox styles tend to be bulkier.
- Material – Aluminum or hard plastic panels offer more rigidity, protection, and aerodynamics than softer vinyl covers. But vinyl costs less.
- Clamp vs. Drill – Clamping systems allow for quicker installation but may not seal quite as tightly long-term versus drilling into the bed sides.
- Access Needs – Determine if you need to quickly access the full bed for hauling or just the front portion more often. This helps choose folding vs. roll-up.
- Budget – Soft vinyl covers start around $200-300 while hard folding panels run $600 on up. Retractable covers cost over $1,000.
- Warranty – Look for at least a 2-year warranty. The best covers offer lifetime warranties against defects.
Finding your optimal balance of price, materials, installation method, and utility takes some upfront research. But choosing the right tonneau can save you money and hassle for years to come.
Expert Tips for Getting the Most from Your Tonneau Cover
Here are my pro tips for maximizing performance and lifespan from your tonneau cover:
- For soft covers, be sure to periodically tighten the tension bands as the vinyl stretches. Keeping the cover taut maintains its aerodynamic profile.
- Folding and roll-up covers shouldn’t be used to haul very heavy items. Distribute weight evenly and tie down gear to prevent excessive stress.
- Hard covers can hold more weight but avoid overloading to prevent denting. Use protective mats under heavy cargo.
- Periodically clean the cover with soap and water to prevent buildup of grime, pollen, and debris which can impede sealing and wear away the vinyl.
- Apply UV protectant to soft covers once or twice per year to prevent sun damage and cracking.
- Don’t rely solely on cover locks to secure gear against theft. Use truck bed locks, cable systems, or other anti-theft deterrents.
- Leave folding covers open during rain showers to allow moisture to drain rather than pooling on top.
- Avoid automatic car washes with brushes that could scratch the surface. Use touchless washes instead.
- Check your owner’s manual for the cover manufacturer’s maintenance tips specific to your model.
Following the care recommendations from your tonneau maker helps ensure you get the longest possible life from your cover. And taking steps to safeguard your cargo gives you maximum security.
Other Truck Bed Covers and Accessories to Consider
Along with tonneau covers, here are some other useful truck bed items to help make the most of your pickup:
Truck Bed Liners
Bed liners protect your truck’s bed from dents, scratches, rust, and other wear. Options include:
- Spray-On – Long-lasting polyurea sprayed directly into your bed for a permanent grip. Withstands heavy use.
- Drop-In – Low-cost plastic liners that drop into your truck bed. Provide basic protection but can slide around.
- Mat – Thick rubber mats that contain small blocks or nubs on the bottom to grip the bed. Easy to install and remove.
Quality bed liners shield your truck from wear and can help maintain higher resale value. For maximum bed protection, spray-on liners are the most rugged and secure option.
Bed Rugs
Cushion your gear and prevent it from sliding with a fitted bed rug. Options include:
- Carpet – Softer feel but less durable. Tends to absorb spills and odors.
- Polypropylene – Resists mold, spills, and mildew. Provides cushioning along with stain protection.
- Hybrid – Combination of carpet top and heavy-duty vinyl bottom. Gives cushioning with more spill protection.
Bed rugs allow you to haul delicate items without scratching while protecting your truck bed from damage. The polypropylene and hybrid options offer the best durability for the money.
Bed Extenders
Increase your truck’s cargo capacity with bed extenders such as:
- Sliding Extenders – Allow you to slide longer cargo forward over the tailgate while still closing it. Can add 1-2 feet of extra space.
- Folding Extenders – Gate extenders that fold up when not needed. Typically add 1-1.5 feet of extra usable space.
