High Loads with Low to Medium Profiles
- Make sure the latch system is properly installed and functioning.
- We recommend installing the reinforcement kit when heavy loads are used.
- Even though the cover holds 2000 pounds doesn’t mean you truck bed rails can support that load.
- Make sure the total weight you put on your cover does not exceed the truck manufacturer’s payload specifications. If you are in an accident (regardless of fault) the insurance company will not cover any loss or damage if the payload has been exceeded.
- Whatever load you place on top of the cover, place the load center of gravity directly over the rear axle; this balances and stabilizes the truck while in motion.
- Place the tie down rings only on panels that have load on top of that panel—this will prevent tie down forces from lifting a panel that has no load on it.
- Ratchet straps are the most common tie down solution. They typically range in load rating from 1000 pounds to 5000 pounds before they break. These numbers are often misapplied. The most important part of securing a load on a moving vehicle is assuring the load does not slide on top of the cover. Rubber L track cover is a good material to use to prevent loaded pallets and other objects from sliding on the cover. The Linex material that is sprayed on top of the cover is textured but is made from polyurethane and very slippery, especially when wet. Preventing a load from sliding is the first step to making sure the load does not slide and remains secure.
- A good rule of thumb is to use 4 tie down straps for any load above 500 pounds. Tighten each strap to between 10 and 20% of the weight of load. Sometimes this can be hard to determine so make sure the ratchet straps are taught and you cannot slide the load if you push on it laterally. We have found the best straps on the market are ShockStraps, they have a polyurethane spring that when stretched 3/8 to 3/4 inch, the tie down force is sufficient.
High Profile Low Loads
- This loading can be the most dangerous if not done properly. This loading type uses light weight loads with large cross sections. Some examples include Kayaks, inflated rubber rafts, bed mattresses, etc.. This loading type combined with high speeds while driving, high cross winds and/or bad roads (pot holes or washboard roads) turns the load into an air foil or airplane wing. Extreme lift is generated (up to several thousand pounds) that can cause the cover, racks and loading to be pulled from the truck. A reinforcement kit is required and this loading type should not be used on freeways. The truck ride should stable and not cause the truck to be difficult to steer.
- Road and weather conditions can change rapidly so paying attention how the truck handles at all times is important.
- Roof top tents are considered High Profile Medium Loads. Most of them are designed with aero dynamics in mind and do not tend to lift off the truck like those mentioned above. When properly secured, freeway driving is acceptable.
