Everything New Owners Need to Know About Travel Trailer Repair

WSI ALM • April 12, 2024

For many people, buying that shiny new RV or travel trailer is one of the most exciting purchases of their lives. An RV is your gateway to highway freedom, allowing you to go anywhere, live anywhere, and maybe even make the world your office as you do business remotely.

However, owning an RV is also a significant responsibility. Their care and maintenance are significantly more complicated than a regular car or truck. So it’s good to learn as much as you can about RV and travel trailer repair and maintenance, to ensure your new vehicle will provide years of enjoyment.

As the top source for RV, motorhome, and trailer upgrades and repairs in Ohio, Mainline RV & Truck Service is here to help! Let's talk about some of the most important elements of maintaining your new RV.


I. Basic Maintenance

In theory, basic maintenance on an RV or travel trailer isn't that much different than a regular vehicle. It's just much larger and more complicated in some respects. However, the essentials remain the same.



·        Tires. Always check the inflation on your tires before any major trip, and ensure they're inflated to the PSI specified in your manual. Also visually check them regularly for signs of damage, such as cracks, bulges, or embedded objects.

·        Fluids. As with a regular vehicle, keeping your oil topped up and regularly changed should be a top priority. However, don't neglect the other fluids, such as your brake fluid and transmission fluid. Keep your manual handy so you know how to check these, and what their proper levels should be.

·        Lights and electrical system. We strongly recommend testing all your lights before a journey, as this will also tell you if your electrical system is working well. Besides the safety factor, having malfunctioning lights on your RV will also attract police - and nobody wants to get pulled over on their vacation.

·        Structural inspection. Motorhomes, RVs, and trailers can be a bit flimsy compared to many smaller vehicles. The roof, in particular, is highly vulnerable to damage because of how big it is. You should regularly do a visual inspection of your trailer, including getting up to the roof, to check for damage or leaks. If there is damage, go to an RV and travel trailer repair center before heading out.

·        Internal cleaning. It's very easy to overlook spills, dropped food, and similar garbage in your trailer. Don't let this happen! It can encourage a pest infestation, such as ants, or even encourage the growth of mold/mildew - not to mention getting smelly, if too much food goes without being cleaned up.

·        Winter storage. Unless you're traveling in the winter, it's a very good idea to winterize your RV and store it indoors during the cold months. You should drain the water and add antifreeze to the plumbing, and also disconnect the battery to be stored indoors where it's warmer.


II. Finding a Great Motorhome and Travel Trailer Repair Shop

The other most important thing to know about maintaining a travel trailer or other RV is that your typical neighborhood garage will not be qualified to work on it. You need to find experienced professionals who specialize in trucks, trailers, and RVs to guarantee you get high-quality repair and upgrade work.

So what are the most important factors when looking for an RV repair center?


1 - Experience with your vehicle

Most car repair shops can't handle RVs, and not all truck-focused shops have experience with motorhomes or travel trailers either. Be sure the shop you choose specifically advertises themselves as working with RVs. You might even want to call ahead, and ask if they have experience with your particular make/model of RV.

Basically, the more experience they have, the better.


2 - Wide variety of services

Ideally, you want a travel trailer repair shop that can be your all-in-one source for parts, accessories, upgrades, or repairs. It's kind of like going to a doctor - you want one you know, and who knows you, to get the best service. Once you find a great shop, stick with it. You'll have better luck that way.


3- On-site emergency services

If your motorhome or RV breaks down on the road, getting it towed can add a significant expense to the repair costs. However, many RV repair centers will have their own on-site services. If they can come to you, that means there's a chance they could repair the problem on the road, without having to tow you at all. If a tow is required, you'll probably pay less than if you called a third-party towing company, since the repair shop is getting your business out of it.


4 - Excellent customer service

Most people have been to a repair shop where it seems like the staff doesn't want to be there, and doesn't care if you're there either. Avoid these places! You want an RV repair center with enthusiastic, motivated workers who make you feel welcome. You'll almost certainly get better services out of them as well.


5 - Costs

We won't lie, RV and travel trailer repairs tend to be expensive. Just expect that going in. Moreover, you really don't want to go cheap on repairs. It's genuinely worth paying a little extra for high-quality parts and service. That'll keep your RV running better, for longer, and can even extend its overall lifespan.

Safe stopping is as vital as engine power when towing a heavy load. Many truck owners overlook trailer brakes until an issue arises. At Mainline RV & Truck Service , we handle various towing setups, primarily electric and surge brakes. Both systems stop a trailer safely, but they operate differently and require separate trailer maintenance approaches. Understanding these differences is essential for road safety. We offer an expert comparison, including specific maintenance needs. Understanding the Fundamental Differences Before discussing what keeps them running smoothly, we should look at how the two systems operate. Electric brakes get their power from an electrical signal sent from the tow vehicle. Pressing the truck’s brake pedal tells the brake controller to send electricity to powerful electromagnets inside the trailer’s drum brakes. These magnets engage an armature plate, which then forces the brake shoes out against the inside of the drum. Surge brakes use hydraulics and work on their own, independent of the truck’s electrical system. Their operation is based on inertia. When the truck begins to slow down, the trailer pushes forward into the hitch. That physical pressure compresses a master cylinder built into the trailer coupler, which then pumps hydraulic fluid to the brake cylinders or calipers. Because one system is powered by electricity and the other by fluid pressure, their weak points and overall maintenance needs are very different. Electric Brakes: Fine-Tuning and Electrical Integrity Electric brakes are standard equipment for nearly all travel trailers and large, heavy-duty flatbed trailers. Since they depend on a good connection between the truck and the trailer, maintenance starts right at the hitch and extends all the way to the brake shoes. Adjusting the "Gain" on Your Brake Controller A key part of operating electric brakes is a setting that you control from inside the truck’s cab, not on the trailer itself. The “Gain” value on your brake controller sets the amount of electrical power sent to the trailer brakes. If the gain is set too low, the truck does all the braking work, which leads to your truck’s rotors getting too hot and your stopping distance increasing. Setting the gain too high means the trailer brakes will lock up easily. Routine truck trailer repair and safety checks involve resetting the gain any time the weight of your load changes significantly. A carefully adjusted gain ensures the truck and trailer brake together, preventing unnecessary stress on either vehicle. Troubleshooting "Grabby" or Locking Brakes A common complaint is that the trailer brakes feel “grabby,” meaning they engage too suddenly or violently with only a little pedal pressure. Often, something is causing a maintenance issue. Common reasons include: Corrosion on the electromagnets: If the trailer has been sitting unused, rust can form and cause the magnets to stick when engaged. Incorrect Gain settings: As mentioned earlier, improper calibration is a frequent culprit. Grease on the shoes: A failed wheel seal can let grease leak onto the brake components, leading to unpredictable braking action. During a professional trailer repair inspection, mechanics remove the drums to check that the magnets are wearing evenly and confirm that no oil or debris is contaminating the friction surfaces. Surge Brakes: Hydraulic Health and Fluid Management Surge brakes are most frequently seen on boat trailers (where electrical parts and water do not mix well) and on rental trailers (because the tow vehicle does not need a specialized controller). Checking Fluid Levels for Surge Couplers Surge brakes primarily fail due to low hydraulic fluid. As the master cylinder in the trailer's tongue or coupler is exposed to constant movement, seals wear, and moisture can enter the system. Routine maintenance requires checking the master cylinder reservoir fluid level; dark or cloudy fluid indicates moisture contamination, necessitating a full flush and replacement. Without sufficient, clean fluid, the surge coupler cannot generate the force required to activate the brakes, leaving the trailer brakeless. Inspecting the Moving Parts of the Coupler Since surge brakes work by the physical “sliding” movement of the coupler mechanism, that sliding part must be kept lubricated and clean. If the coupler rusts or jams up, the brakes might stay applied even when you are driving, or they may completely fail to engage when you slow down. The Common Ground: Shoe Adjustment and Wear The way the brake shoes are moved might be different, electricity for one, hydraulics for the other, but the shoes themselves need manual upkeep in both systems. Shoe Adjustment Intervals for Heavy-Duty Trailer Repair While some newer trailers feature self-adjusting brakes, many heavy-duty models still need manual adjustment. As the friction material on the brake shoes wears away, the space between the shoe and the drum increases. The result is a noticeable delay in braking response. For dependable safety, we advise having your brake shoes inspected and adjusted every 3,000 to 5,000 miles. During a trailer maintenance appointment, a technician uses a “star wheel” adjuster to move the shoes closer to the drum. This ensures that the trailer brakes immediately when you press the pedal. Which System is More Maintenance-Intensive? Surge brakes demand hands-on maintenance (checking fluid/grease). Electric brakes risk less obvious electrical failures (wiring, fuses, ground). For heavy loads, electric brakes offer a manual override for sway correction, but require electrical knowledge for troubleshooting. Surge brakes are simpler for the driver but need constant hydraulic system vigilance to prevent failure. Summary Checklist for Trailer Safety Keep your trailer operating at its best by following these simple guidelines: Annual Inspections: Have a certified professional examine your brakes and wheel bearings at least once a year, regardless of how many miles you have driven. Test Before You Tow: Always perform a quick “tug test” to confirm the brakes are working before you get out on the road. Watch for Corrosion: Check the 7-way electrical plug (for electric brakes) or your brake fluid lines (for surge brakes) for any signs of rust or damage. Listen: Squeaking, grinding, or clicking sounds are the most immediate indicators that truck trailer repair is necessary. Contact Mainline RV & Truck Service for Trailer Repair & More!
