What Should You Do If Your RV Breaks Down on The Road?

Mainline Truck Team • September 1, 2022

A great RV can last for many miles and offer you years of on-road and camping fun, but there's also a lot that can go wrong. RVs are far more complicated than standard cars and trucks, with numerous extra systems that can develop issues while you're on a trip. Beyond usual issues with engines, brakes, and suspension, you can also have problems with the electrical system, the refrigeration, and even the sewage system.


Do you have plans in place to prevent a breakdown from being a disaster? Do you have a clear idea of what to do if you're stuck by the side of the road and need RV repair? In this guide, we'll talk about how to prepare yourself and minimize the inconvenience of an RV breakdown.


And remember - if you're ever in Ohio, you can always bring your RV to Mainline RV & Truck Service for the best in service, repairs, and upgrades!


I. Be Prepared Before You Set Out

The last thing you want is to end up stuck with a broken down RV without having made plans ahead of time.  Being prepared will do a lot to reduce problems, speed up your RV repairs, and even help keep you safe.


1 - Have warning/safety items onboard

You should never go on a long trip without bringing along some warning triangles, orange cones, or marker flares. Be sure you have some in your RV, stored someplace that's easy to reach when you need them.  Remember, at night you will be hard to see - you need those warning markers to protect yourself from traffic.

However, be aware of your environment. If you smell gasoline or natural gas/propane, do not use a marker flare. There's too much chance of it igniting something, even if it's several feet away from the RV.


2 - Have a full tool kit

Also, you should have a good tool kit stowed away, in case the problem is something that's easy to fix.  We particularly recommend bringing:

  • Flashlight
  • Screwdriver Set
  • One or more adjustable wrenches
  • Tire pressure gauge
  • Socket and ratchet set
  • Allen wrenches
  • Extra fuses for onboard electronics
  • Jack
  • Tape measure
  • Duct tape
  • Zip ties


You'd also do well to invest in a small air compressor, so you can refill your tires on the road if needed.  Plus, keep an eye on your spare tire and make sure it's in good shape before setting off on each adventure.


If you're driving in the winter, we also recommend having some cold-weather survival gear such as heat packs, heavy clothes, and sleeping bags. Your RV will provide some shelter, but if the electronics fail, you still need to keep yourself warm.


3 - Know your warranties

It's a good idea to keep your RV's service warranty in the same place you keep your manual and registration. Many companies offer roadside support services as part of their warranty, although it's not universal. Being familiar with your warranty can potentially save you some money if you don't have to call in a third-party tow for RV repair service.


4 - Subscribe to a roadside service, if needed

If your warranty doesn't offer any roadside support, it's a very good idea to sign up with a group like Triple-A as a backup plan. Prices are typically pretty low for year-round coverage, and if you ever get stuck, that extra 'insurance' will be well worth the money. The further from home you're going, the more important it is to have a backup plan in case of accident or mechanical problems.


Of course, whether you have warranty support or you're using a different roadside service, be sure to keep the appropriate phone numbers somewhere safe and easily accessible. Keeping them in your wallet next to your driver's license is a good idea if you spend a lot of time in your RV.


5 - Know your limitations

Thanks to nearly ubiquitous Wi-Fi and the Internet, it's possible to look up repair instructions for virtually every type of mechanical failure you might have. But know what you can and can't fix yourself.  If you attempt a DIY repair that's beyond your skill level, you could end up wasting hours, and only end up with more problems than you started with.


II.  What to Do If There's an Emergency

So, what should you do if you suffer mechanical failures on the road?


1 - Assess if you can keep driving

There are many problems with an RV that won't immediately stop you from being able to drive, such as electronic problems in the living area. Don't pull over unless you absolutely have to. If it's a minor issue, just look for the nearest RV repair shop and head for it ASAP.


But if it's a more critical issue such as engine failure, brake failure, or a tire blowout...


2 - Find a safe place to pull over

You want to be as far onto the shoulder, or even onto the grass, as possible - but avoid stopping on an incline, or on the backside of a hill. The further you are from the road, the safer you'll be. Don't assume other motorists will see you. Some people are amazingly unobservant, and you want to be well out of their way.


3 - Put on your hazard lights and put down your warning gear

Don't park on the side of the road for any length of time without making yourself as visible as possible.  These should be spaced out a good ways - up to 100-200 feet from your vehicle, to give oncoming traffics as much warning as possible.


4 - Keep passengers in the vehicle (unless you smell gas)

If you're having mechanical problems, only the most competent or able-bodied adults should leave the vehicle. This is particularly important if you have kids onboard. Don't let them wander around, that's just asking for more trouble.  Ideally, they should stay in their seats, belted, just in case there's a collision.


However, the exception is if you smell gasoline or gas/propane/etc. If there's a fire risk, get people well away from the RV - but keep them away from the road.


5 - Try to diagnose the problem

If possible, determine what's wrong with your RV, or at least have a general idea of the issue. Even if you can't fix it yourself, you'll speed up the repair process if you can tell the repair crew ahead of time what's wrong. They'll be able to bring the right tools and parts that way.


6 - Call for help

Fortunately, cell service is becoming so commonplace that it's getting downright hard to find areas without service. Unless you're deep in a forest or state park, you'll probably be able to get enough bars to make a call. This is the time to pull out those phone numbers for your warranty service and/or roadside assistance and call in some backup. 


7 - How to find other help

What if you lack any roadside protection, or forgot the phone numbers? You've got a couple of options here.

First, whenever you stop at an RV park, ask them for recommendations for local RV repair shops. You never know when you might need a tow or repair, and their suggestions are probably going to be good ones. In many cases, RV parks give out fliers with exactly the sort of information you need, so try to collect them as you go.


Otherwise, you'll be turning to Google. You want a tow or repair service that:

  • Has 4–5-star ratings
  • Has good written reviews 
  • Has been in business for years, or decades
  • Has certifications from the manufacturer to work on your vehicle


Remember to look specifically for RV repair shops. Standard car/truck repair services might try to fix your RV, but they need experience with RVs for you to be able to trust their work.


8 - Keep an eye on the road while you wait

While it’s tempting to hang out in your RV while you wait for your service vehicles to arrive, the safer option is to stay outside where you can watch traffic. This ensures you'll see the help arrive, and they'll see you, without overshooting. Also, you'll be more visible and help prevent any other motorists from causing problems or accidentally hitting the RV.

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!
