Bighorn RV’s are some of the most reliable recreational vehicles on the market, but like any vehicle, they may occasionally experience a few issues. This guide is designed to help you identify and fix common problems that can arise with your Bighorn RV.
Identifying Problems
The first step in diagnosing and repairing an issue is identifying it. The best way to do this is by closely observing your RV while it is running. Pay attention to anything unusual such as noises or vibrations coming from the engine bay or smells coming from vents or air intakes. Other tell-tale signs include visible smoke coming out of exhaust pipes, lighting fluctuations inside the cabin, and difficulty starting or maintaining speed during operation.

Common Problems and Solutions
- Water leaks – This is one of the most common problems with Bighorn RVs. Water can leak from faulty seals, windows, doors, and vents. Inspect these areas for cracks or tears and make sure all gaskets are properly sealed to prevent water from entering the vehicle.
- Engine overheating – If your engine is running too hot, it could be due to a clogged radiator or an issue with the cooling system. Make sure your coolant levels are correct and that there are no air bubbles in the system. If this does not fix the issue, you may need to take your RV into a professional mechanic for further investigation.
- Electrical faults – Faulty wiring or circuits can cause electrical issues such as flickering lights or short-circuits. Check all wiring for signs of damage and ensure that fuses and breakers are in working order. If the problem persists, consult a professional to identify the underlying cause.
- Fuel line blockages – A blocked fuel line can prevent fuel from reaching the engine, resulting in poor performance or difficulty starting up. Make sure your fuel filter is clean and free of debris. In some cases, you may need to replace the entire fuel line if it is too clogged or damaged to be repaired.
- Slide outs won’t go in or out – This is usually caused by faulty slide out mechanisms or damaged control units. Inspect the motor and controls for signs of wear and tear, and make sure that all cables are connected properly. If the issue persists, you may need to replace the entire mechanism or contact a professional technician for assistance.
- Furnace doesn’t work – If your furnace is not working properly, it could be due to a clogged filter or a faulty ignitor. Replace the filter and check the ignitor for signs of wear and tear. If these do not fix the issue, you may need to contact an RV repair specialist for further assistance.
- Refrigerator stopped cooling – If your refrigerator is not cooling properly, it could be due to a faulty thermostat or a clogged condenser coil. Make sure the thermostat is set correctly and clean the condenser coils with a vacuum cleaner or compressed air. If these steps do not resolve the problem, you may need to contact an RV repair specialist for further assistance.
- Awning won’t retract – This can be caused by a faulty motor or mechanism. Inspect the motor and control unit for signs of wear and tear, and make sure that all cables are connected properly. If the issue persists, you may need to replace the entire mechanism or contact an RV repair specialist for assistance.
How to properly maintain your RV to avoid any major issues down the road

Regular maintenance and care is key in keeping your Bighorn RV running properly. Here are some simple tips to help you keep your RV in top condition:
- Perform routine inspections – Regularly inspect your RV for any signs of wear and tear, such as fraying wiring or damaged components. Look closely at the roof, windows, doors, and vents for signs of water damage. Check all hoses, belts and filters to make sure they are free of debris or blockages.
- Clean regularly – Make sure to clean the exterior of your RV on a regular basis with a mild soap and water solution. This will help remove dirt and grime that can build up over time, reducing the risk of damage from the elements. Additionally, fill the fuel tank with a quality fuel when possible to help reduce build up inside of it.
- Change fluids – Make sure to change your engine oil, transmission fluid and other vital fluids according to manufacturer guidelines. This will help keep your RV running smoothly and reduce the risk of breakdowns in the future.
- Check tire pressure – Ensuring proper tire pressure helps extend the life of tires and improves your RV’s handling on the road. Make sure to check your tire pressure regularly and inflate as needed to maintain optimal performance.
- Have regular services performed – Taking your RV in for regular maintenance can help identify any potential problems before they become serious issues. Services typically include changing the air filter, inspecting the brakes and suspension system and checking the battery, among other things.
By taking these steps, you can ensure that your Bighorn RV remains in good working order for years to come. Regular maintenance and care can help prevent major issues down the road and keep you safe on the roads. If any major issues do arise, consult a professional to identify the underlying cause.
