Hauling gear, supplies, or even just a load of yard waste in your truck bed? The open road, unexpected weather, and even just a bumpy trail can quickly turn your carefully loaded items into a scattered mess or, worse, a roadside hazard. That’s where a trusty tarp comes in.
You might think throwing a tarp over your cargo is simple, but there’s an art and a science to it. Done right, it keeps your valuable cargo safe, dry, and exactly where you left it. Done wrong, you risk losing items, damaging your truck, or even causing an accident.
This guide from FatBoysOffroad will walk you through everything you need to know about how to cover a truck bed with a tarp effectively. We’ll share expert tips, essential gear, and step-by-step instructions to ensure your load is secure, whether you’re heading to the campsite or the construction site.
Why You Need to Know How to Cover a Truck Bed with a Tarp
Your truck is a workhorse, designed to carry heavy loads and tackle tough terrain. But an uncovered bed leaves your cargo vulnerable. Understanding proper tarping techniques is crucial for several reasons, protecting both your items and those around you.
Protecting Your Cargo from the Elements
Imagine driving through a sudden downpour with an open bed full of camping gear or tools. Rain, snow, and even intense sun can damage sensitive items. A properly secured tarp acts as a protective shield, keeping your cargo dry and safe from UV rays.
Dust and road grime are also constant threats. Covering your load ensures that everything arrives at your destination clean and ready for use. This is especially important for items like furniture, electronics, or anything you want to keep pristine.
Securing Your Load for Safe Travel
Loose items in a truck bed are a major safety hazard. At highway speeds, a strong gust of wind can easily lift lightweight objects, turning them into dangerous projectiles. Even on rough off-road trails, unsecured gear can bounce out, getting lost or damaged.
Properly securing a tarp prevents cargo from shifting, falling out, or creating dangerous debris. It’s not just about protecting your stuff; it’s about keeping other drivers, riders, and pedestrians safe on the road. Always prioritize safety over speed when loading your truck.
Choosing the Right Tarp and Gear for Your Truck Bed
Before you even think about how to cover a truck bed with a tarp, you need the right equipment. Not all tarps are created equal, and having the correct tie-downs is just as important as the tarp itself.
Tarp Materials and Sizes
Tarps come in various materials, each suited for different tasks:
- Polyethylene (Poly Tarps): These are the most common, lightweight, and affordable. They’re good for general-purpose use, offering decent water resistance. Look for thicker mil ratings for better durability.
- Canvas Tarps: Heavier and more durable, canvas tarps offer excellent breathability, preventing condensation. They’re great for protecting furniture or items that need airflow, but they aren’t fully waterproof unless treated.
- Vinyl Tarps: The heaviest-duty option, vinyl tarps are incredibly strong, tear-resistant, and completely waterproof. They’re ideal for heavy loads, long hauls, or extreme weather conditions.
Size matters: Your tarp needs to be large enough to completely cover your cargo and extend down the sides of your truck bed by at least 1-2 feet. This extra material is crucial for creating a secure “envelope” and preventing wind from getting underneath.
Essential Tie-Down Equipment
A tarp is only as good as its tie-downs. Here’s what you’ll need:
- Bungee Cords: Best for lighter loads and quick, temporary securing. They offer elasticity to absorb movement but can snap if overstretched or worn.
- Rope: Versatile and strong, rope allows for custom knot-tying and securing. Practice your trucker’s hitch for maximum tension.
- Ratchet Straps: The gold standard for heavy or bulky loads. Ratchet straps provide immense tension, keeping your tarp and cargo absolutely secure. They are non-elastic and very strong.
- Tie-Down Anchors/Cleats: Most truck beds have factory tie-down points. If not, consider adding aftermarket anchors or cleats for more secure attachment points.
Always inspect your tie-downs before each use. Frayed ropes, stretched-out bungees, or damaged ratchet straps should be replaced immediately.
Step-by-Step Guide: How to Cover a Truck Bed with a Tarp Like a Pro
Now that you have your gear, let’s get to the practical application. Follow these steps for a secure and professional tarp job.
Prepping Your Truck Bed and Cargo
First, clear any sharp edges in your truck bed that could tear the tarp. If you’re hauling items with sharp corners, use old blankets or cardboard to pad them. This small step can significantly extend your tarp’s life.
Next, load your cargo evenly. Distribute weight to prevent shifting. Place heavier items at the bottom and center, lighter items on top. Try to keep the top of your load as flat as possible; a high, pointed peak makes tarping more difficult and creates wind resistance.
Positioning the Tarp Correctly
Unfold your tarp and drape it over your cargo. Ensure it covers the entire load and extends well down the sides and ends of the truck bed. Aim for an even overhang on all sides.
For best results, try to position the tarp so that any seams or folds run parallel to the direction of travel. This minimizes resistance and prevents wind from catching and flapping the tarp. If possible, have the tarp extend slightly over the tailgate and the cab side of the bed.
Mastering Your Tie-Down Techniques
This is the most critical part of how to cover a truck bed with a tarp. Proper tension and secure attachment points are key.
- Start with the Front (Cab Side): Secure the tarp’s front edge first. Use bungee cords or rope to attach the tarp grommets to the front tie-down anchors in your truck bed. Pull it taut, but don’t over-tighten yet.
- Move to the Back (Tailgate Side): Next, secure the rear edge. Pull the tarp firmly over the tailgate and attach it to the rear tie-down points. If your tarp is long enough, you can even tuck it under the tailgate for extra security before closing the tailgate.
- Secure the Sides: Work your way down each side, alternating between left and right. Attach bungee cords, rope, or ratchet straps from the tarp’s grommets to the side tie-down points. Pull each tie-down tightly, creating a smooth, drum-like surface on the tarp.
- Eliminate Slack: Once all points are secured, go back and check for any loose spots or flapping areas. Adjust your tie-downs, adding more if necessary, to remove all slack. The tarp should be tight and snug against your cargo, almost like a second skin.
- Cross-Tensioning (Pro Tip): For maximum security, especially with heavy loads or long distances, use longer ropes or ratchet straps to create “cross-tension.” Run a strap from a front corner grommet diagonally to a rear side tie-down point, and repeat on the other side. This creates an X-pattern that pulls the tarp even tighter against the load.
Remember, the goal is to create a secure, aerodynamic cover that won’t flap, lift, or allow water to pool.
Advanced Tips for Securing Your Truck Bed Tarp
Beyond the basics, there are a few pro moves that can make your tarping even more robust for challenging conditions.
Dealing with High Winds and Highway Speeds
High speeds generate significant wind force. For highway travel, you’ll want extra security. Consider using only ratchet straps for your primary tie-downs, as they provide superior, non-elastic tension. Avoid using bungee cords alone for highway speeds, as they can stretch and fail.
If your load is very tall, the tarp might create a sail effect. Try to keep the load profile as low as possible. When securing, ensure the tarp wraps well under the load or past the bed rails. This creates an “over-and-under” effect that locks the tarp in place, preventing wind from getting underneath and lifting it.
Customizing for Awkward Loads
Not every load is a perfect rectangle. If you’re hauling irregularly shaped items, like a motorcycle or a stack of firewood, you might need to get creative. Use smaller pieces of tarp or heavy blankets to cover individual protrusions before placing the main tarp over everything.
For very odd shapes, you might need to use a cargo net under the tarp to help contain the load, then secure the tarp over the net. This provides an extra layer of containment. Always pad sharp edges to prevent tears, especially when dealing with unique cargo.
Preventing Water Pooling
A common issue with tarping is water pooling, especially during rain. This adds weight, can seep through, and stretches the tarp. To prevent this, try to create a slight “peak” in the center of your load, allowing water to run off the sides.
If your cargo is relatively flat, you can place a bucket or a spare tire in the center of the bed before draping the tarp. This creates a dome shape that encourages water runoff. Ensure the tarp is pulled tight enough that it doesn’t sag excessively between tie-down points.
Common Mistakes to Avoid When Covering Your Truck Bed
Even seasoned DIYers can make simple errors that compromise their cargo’s safety and security. Learn from these common pitfalls.
Overlooking Safety Checks
Never skip the final walk-around. After you think you’re done, tug on each tie-down. Wiggle the tarp. Does anything feel loose? Is there any excessive flapping?
Check your knots if you’re using rope. Ensure bungee cords are not stretched to their absolute limit, which can cause them to snap. Ratchet straps should be free of twists and securely latched. A quick inspection before you hit the road can prevent major problems down the line.
Using the Wrong Gear
Trying to secure a heavy load with flimsy bungee cords is a recipe for disaster. Using a tarp that’s too small leaves gaps for weather and wind to intrude. Always match your equipment to the job.
Investing in quality tarps and tie-downs is a smart move for any truck owner. They last longer, perform better, and provide peace of mind. Don’t compromise on safety by using inadequate or worn-out gear.
Frequently Asked Questions About Covering Your Truck Bed
How tight should a tarp be on a truck bed?
The tarp should be pulled as tight as a drum. There should be no visible slack, sagging, or flapping areas. A well-secured tarp will not billow in the wind, even at highway speeds.
Can I use just bungee cords to secure a tarp?
For light, non-critical loads on short, low-speed trips, bungee cords can be sufficient. However, for heavier loads, longer distances, or highway speeds, always use stronger options like rope with proper knots or, ideally, ratchet straps for maximum security. Bungees can stretch, degrade, and fail under stress.
What if my tarp doesn’t have enough grommets?
If your tarp lacks sufficient grommets, you can purchase tarp clips or clamps. These attach to any edge of the tarp and provide a secure loop for your tie-downs. Space them evenly to distribute tension and avoid tearing the tarp material.
How do I prevent my tarp from tearing?
Prevent tears by padding any sharp edges on your cargo with blankets, cardboard, or foam. Avoid over-tightening the tarp, especially at grommet points. Use the correct size and material tarp for your load, and always inspect your tarp for small tears or weak spots before use.
Is it legal to drive with a tarp covering my truck bed?
Yes, it is generally legal to drive with a tarp covering your truck bed, provided the load is fully secured and nothing can escape. In fact, many states have laws requiring loads to be covered or secured to prevent debris from falling onto the roadway. Always check your local and state regulations for specific requirements regarding load securement.
