Tonneau Covers - Frequently Asked Questions 
THE 4WAY TONNEAU COVER VS. THE COMPETITORS
COVER CONSTRUCTION / COVER CHARACTERISTICS
OPERATION/FUNCTION OF THE COVER
  • How easy is it to remove the cover? Please describe.
    Simply unlock the 4 locks, and lift the cover straight up and off of your truck. All that will remain will be the mounting rails with the torsion bars (coming off of the edges of the mounting rails). If you will be removing the cover for a long period of time, just simply loosen up the clamps and remove the mounting rails so they will be protected.

  • How much force does it take to lift open the cover?
    Not much. The torsion bars help you to lift the cover to the height required. This is basically a "lift assist" setup. You must supply some force, but not much.

  • When the cover is closed, does it improve my gas mileage while traveling?
    YES. Extensive Wind Tunnel Testing has proven that our cover will improve the aerodynamics of your truck and therefore improve fuel economy. We make no guarantees as to how much the cover will play in improving your gas mileage. However, in highway driving, many of our customers have experienced as much as a 2 - 3 miles per gallon improvement. If you use the smaller number of 2 miles per gallon as the figure to calculate cost savings, the savings can add up.

    For example, if your truck currently gets 16 mpg on the highway without the cover, and gets 18 mpg with the cover, you have improved your gas mileage by 12.5%. Assuming you drive 10,000 highway miles per year. At 16 mpg, you will buy 625 gallons of gas per year. If you save 12.5%, that means you will buy 78.1 gals. per year less. At $1.50 per gallon of gas, that is a savings of $117.15 per year or about $10/month (and this does not include the savings you might have in any non-highway or city driving). In this scenario, if you keep the truck for 4 years or 48 months, the cover pays for itself! If you drive 20,000 highway miles per year, in this scenario, you would pay for the cover in 2 years! With $2.00 and more per gallon of gas, you would save 35% more than the amounts calculated above (Approximately $150/year at 10,000 mi/year and $300.00 for 20,000 mi/year).

  • Can I travel with the cover open from the back?
    It is not recommended to travel with the Tonneau cover open in the front or rear positions. The reason for this is obvious in the front position. In the rear position, the wind force placed on the tonneau cover could cause it to bend excessively in the middle. If you stayed in town and traveled at speeds under 25 mph, this would not likely be a problem however, keep in mind that our warranty will not cover damage if the customer travels with the tonneau cover open in the rear position.

  • Can I travel with the cover open from the side?
    Yes. As long as the tether straps are completely tight and you do not travel in excess of 50 mph. Some other common sense considerations should be given when deciding to travel on the highway with the tonneau cover open. The most obvious of course is the cross wind conditions. Wind created by forward speed of the vehicle will not harm the tonneau cover when open in the side positions.

  • Can I travel with the front of the cover open?
    NO! If you attempt to travel with the front of the cover open with the cover resting on the tailgate, you will create a "parachute effect." You should never travel with the cover open in this position as when you travel, the flow of air goes over the hood, windshield, and roof and then comes racing down the back glass of the truck into the truck bed. The force of this air can be extremely powerful and if you travel with the front panel laying on top of the back panel, this powerful air flow will now travel under the cover and will apply an enormous amount of upward pressure to the cover. This is the same concept behind why many people lower their tailgate to increase mileage on long trips as this reduces the air resistance (drag) of the air flowing into the truck bed while traveling.

INSTALLATION
  • How long does it take to install a cover?
    The cover takes approximately 30-45 minutes to install.

  • I have a sprayed-in bedliner that goes over the side rails. What do I need to do before installing the cover.
    If you have sprayed on bedliner, this is absolutely no problem! Just simply install as normal.
    Back to Top


  • I have a plastic bedliner in my truck. Do I have to make any modifications to the bedliner to install the cover?

    IF PLASTIC BEDLINER GOES UP AND OVER THE FRONT RAIL: If you have a plastic bedliner that goes only over the front rail and/or the tailgate, this is NO PROBLEM! You will not need to make any adjustments to the plastic bedliner to install this cover.

    IF YOU HAVE A TAILGATE PROTECTOR: Tailgate protectors rarely present any problem for this cover. If you have a factory installed tailgate protector, these will not be a problem. If as a part of your bedliner package or as an additional accessory to your truck, if you have installed a tailgate protector, these are rarely a problem also. With the tailgate closed, if the tailgate protector adds more than 3/8" to the "top" or edge of the tailgate, you will have to remove and/or replace the tailgate protector. However, it is very rare that a tailgate protector is thicker than 3/8".

    IF PLASTIC BEDLINER OVER SIDE RAILS: The biggest concern with Plastic bedliners is whether or not you can install the clamps under the bed rail. You may have to cut out/drill out some small holes in the liner to fit the clamp through. but otherwise should not be a problem.

  • Can you install the cover over a sprayed-in bed liner that has already been sprayed over the rail?
    Absolutely. The 4Way Tonneau Cover installs perfectly on trucks with sprayed in bedliners that go over the rails.

  • Do the factory installed side rail bedliners on the 97 thru current Fords and the 99-current Super Duty Fords need to be removed?
    No. Just simply install the cover directly on top of these factory installed side rails for a perfect fit.

  • Do the factory installed side rail covers on my Full Size Ford or my Toyota Tundra, or my Nissan Titan need to be removed?
    No. We have designed the covers for these trucks to install directly onto the rail covers without you having to remove them.
    Back to Top


  • Are any holes drilled in the truck?
    NO. The 4Way Tonneau Cover is a completely drill-less installation.

  • Which model of this cover is the easiest to install?
    All cover installations are exactly the same. All are drill-less, goof proof, and very easy to install.

  • If I install your cover, can I keep my toolbox on the truck?
    We can custom build a tonneau cover that will butt up to the over the rail tool boxes. You will need to fill out the Custom Cover Information Form. Click on Custom 4-Way Tonneau Cover Form for a printable pdf form.

  • I plan to occasionally remove the cover and put a "slide-in camper" into the truck bed. Will I need to remove the mounting rails?
    You would have to remove the mounting rails in this case because of the torque rods.
