If you're tired of cranking that manual arm every time you load up, installing an electric tarp motor kit is honestly one of the best favors you can do for your back. Let's be real for a second—nobody actually enjoys hopping out of the cab in the pouring rain or freezing wind just to wrestle with a stubborn tarp. It's one of those chores that feels fine the first few times, but after a long day of hauling, it's the last thing you want to deal with. Switching to an automated system isn't just about being "lazy"; it's about efficiency and, more importantly, staying safe on the job.
Why You Should Ditch the Manual Crank
The biggest reason most guys look into an electric tarp motor kit is the sheer convenience. Imagine finishing a load, hitting a switch from the comfort of your seat, and watching the tarp slide perfectly into place. It takes seconds. Compare that to the five or ten minutes of fumbling with a manual handle, especially if the tension isn't quite right or the wind is trying to turn your tarp into a sail.
Beyond just the "cool factor" of having a motorized trailer, there's a massive safety element here. Climbing up on the side of a trailer or hanging off the back to get leverage on a manual crank is a recipe for a slip-and-fall. This is especially true in the winter when everything is covered in a thin layer of ice. When you automate the process, you keep your boots on the ground—or better yet, your butt in the driver's seat.
What Actually Comes in the Kit?
If you've started shopping around, you'll notice that an electric tarp motor kit usually comes as a bundle. You aren't just getting a motor; you're getting the whole nervous system for your trailer's covering. Generally, you'll find the motor itself (which is the heart of the operation), a chrome or plastic cover to keep the weather out, a switch kit for the cab, and a bunch of wiring.
Most of these motors are 12V high-torque beasts. They have to be. They're pulling against heavy fabric and often fighting wind resistance or debris. You'll also see different gear ratios, like 60:1 or 90:1. The ratio basically determines how much "muscle" the motor has versus how fast it moves. If you've got a massive grain trailer or a heavy-duty dump bed, you're going to want that extra torque to make sure the motor doesn't burn out trying to move a heavy load of wet gravel.
The Reality of Installation
I won't sugarcoat it—putting in an electric tarp motor kit takes a bit of mechanical know-how, but it's definitely a DIY job if you're handy with a wrench and a wire stripper. The hardest part usually isn't mounting the motor; it's running the wires. You've got to get power from the battery all the way back to the motor, and you want to do it in a way that doesn't leave wires dangling or prone to getting snagged on road debris.
A pro tip for anyone doing this themselves: pay attention to your ground. Most electrical issues with these kits come down to a bad ground connection. Since trailers take a lot of abuse and deal with a ton of vibration, a loose wire will drive you crazy with intermittent power loss. Use plenty of zip ties, and if the kit doesn't come with a high-quality circuit breaker, go ahead and buy one. It's way cheaper to flip a breaker than it is to replace a fried motor because something got jammed.
Is It Worth the Investment?
When you look at the price tag of a solid electric tarp motor kit, it might give you a moment of pause. It's an investment, for sure. But you have to look at it in terms of "time is money." If you're making six or seven hauls a day, and you save five minutes on each end of the trip, you've just clawed back nearly an hour of your day. Over a month, that's a lot of extra productivity.
Then there's the wear and tear on your body. Shoulder injuries are common in this industry, and the repetitive motion of cranking a heavy tarp doesn't help. If spending a few hundred bucks on a motor kit prevents a doctor's visit down the road, it's paid for itself ten times over. Plus, it usually adds a bit of resale value to the rig. A buyer is always going to pick the trailer with the push-button tarp over the one that requires a workout.
Choosing the Right Motor for Your Load
Not all motors are created equal. When you're looking for an electric tarp motor kit, you need to match the specs to what you're actually hauling. If you're running a short dump truck, a standard motor might be fine. But if you have a 40-foot trailer, you need something with serious guts.
Check the warranty too. These things live in a brutal environment. They get blasted by road salt, pelted by rocks, and soaked by rain. A company that stands behind their gear with a three or five-year warranty is usually a better bet than a "no-name" bargain motor from a random site. You want a motor with a sealed housing and maybe some chrome plating or a heavy-duty plastic shroud to keep the internals dry.
Maintaining Your Motor Kit
Once you've got your electric tarp motor kit installed, don't just forget about it. Like anything else on a truck, a little bit of TLC goes a long way. Every few months, it's a good idea to check the mounting bolts. Vibration is the enemy of all things mechanical, and those bolts can wiggle loose over time.
Keep the electrical connections clean. If you see a bit of green corrosion starting to form on the terminals, hit it with some contact cleaner and apply a bit of dielectric grease. This keeps the moisture out and ensures the motor gets all the juice it needs to spin. Also, keep an eye on the tarp's tension. If the tarp is too tight, the motor has to work twice as hard, which can lead to overheating. If it's too loose, the wind will catch it and put weird stresses on the motor shaft.
Common Troubleshooting Tips
Sometimes things go sideways. If you hit the switch and nothing happens, don't panic and assume the motor is dead. Nine times out of ten, it's a blown fuse or a tripped breaker. Check your power source first. If the motor is making a clicking sound but not turning, it might be jammed, or the battery voltage might be too low.
If the motor seems sluggish, it's usually a sign of a bad connection or a wire that's too thin for the distance it's running. Voltage drop is a real thing. If you ran thin 14-gauge wire to the back of a long trailer, that motor is going to struggle. Most electric tarp motor kit instructions will tell you exactly what gauge wire you need, so don't try to get cheap and use whatever you have lying around the shop.
Final Thoughts on Going Electric
At the end of the day, an electric tarp motor kit is one of those upgrades that you'll wish you had done years ago. It's about making the workday a little less exhausting and a lot more efficient. Whether you're hauling grain, gravel, or scrap metal, being able to cover your load with the press of a button is a total game-changer.
Sure, there's an upfront cost and a Saturday afternoon spent under the trailer doing the wiring, but the first time it starts pouring rain while you're safely tucked inside your cab, you'll know it was worth every penny. It's a simple upgrade that delivers massive returns in comfort and safety. So, if you're still out there cranking away by hand, maybe it's time to give your arms a break and let a motor do the heavy lifting.
