10 Bighorn RV Problems And Solutions

The Bighorn RV designed, built, and equipped their RVs to handle the harshest environment. However, despite its incredible reliability, some common problems always emerge, and they annoy the owners or users.

In this section, I have extensively discussed 10 problems you will likely face when using this RV and their solutions. Read on for more insights:

Problem 1: Electrical Issues

The Bighorn RV’s parts and appliances, such as the air conditioner, furnace, lights, and some of its functionality like the transmission and ignition, depend heavily on electricity. So, electrical issues can result in breakdowns or inconveniences

Voltage issues and faulty wiring or problems can cause electric problems such as sudden power cuts and lights out. Other major causes include:

  • Problems in power sources
  • Physical damage to electric parts
  • Issues in breakers and fuses
  • Abnormal current draws in electric appliances
  • Issues occurring in the 12-volt system

When facing electrical issues, you can apply these solutions to diagnose and fix them:

  • Identify the Blown Fuses: First, examine and read the RV’s electricity usage, and find the blown fuse or damaged. This will display and identify if the fuses blow.
  • Check the Breakers: Examine the breakers. Make sure the breakers are turned on and not off. Also, check for physical damage or faults in the electric parts.
  • Professional help: In case the problem is not a circuit breaker or fuse, I recommend contacting a professional as treatment can be dangerous.


The price of breakers and fuses determines the cost of solving your RV’s electrical issues. The price range for fuses ranges between $2 to $65, and breakers cost between $10 and $50. However, if you enlist the help of an electrician it could cost you an extra $100 to $250 dollars.

Problem 2: Ice Makers Leak

In my road trips, I realized ice makers are a great addition, especially during summer, as they enhance your comfort during the journey. The typical signs of a malfunctioning ice maker include failure to freeze properly, taking more time to freeze, and water leaks.

Icemaker problems mainly originate from physical damage and electrical surges. Other common causes of ice maker issues include:

  • Insufficient water supply
  • Electrical Faults
  • Freezing Component Failure

To fix ice maker leaks, check the supply tank and water valve. You can follow these steps to diagnose a few issues:

  • Access your ice maker’s bottom vent and look for faults.
  • After the diagnosis, detach the main panel and search for issues within the water valve.
  • Spot a bluish water valve in the Ice maker’s chamber and check the water supply.
  • If the water valve doesn’t supply water, replace it.

Note: If the problem persists, the problem may be in the electrical circuits. Look for malfunctions using a multimeter, but to cover electrical issues I recommend contacting a professional.


If your ice maker is damaged, buy and install a new one. You can pay up to $550 for a new ice maker, but getting a decent one within the $150 to $250 range is possible.

Problem 3: Water Leaks

The Bighorn RV’s bad drainpipe has tainted its reputation, as it is known for leaking. The leaking water always pours on the carpet, trunk, and other parts of RV’s floor, inducing floor deterioration and molding.

Some common causes of water leaks include:

Problem 3: Water Leaks
  • Excessive Water Pressure
  • Loose Taps
  • Loose Pipes
  • Malfunctioning Toilet System
  • Drainage Pipe Leaks

To deal with water leaks on your Bighorn RV:

  • Search for leaks in the water lines and pipes.
  • Tighten the lines and pipe if you find leaks, look for leaky taps, and immediately repair them.
  • Fix any discovered holes in the water lines immediately and replace pipes with corrosion or internal damages.

Important! Failure to resolve water leakage from damaged pipes will cause fungus infection and a stinky smell.


You will have to replace your toilet system if it is faulty at a cost ranging between $150 to $1000. Repairing taps and pipes will cost $100.

Problem 4: Tire and Wheel Problems

Like other RV parts, the wheels and tires also lose their performance and integrity with time, creating a significant concern for most Bighorn motorhome owners. Wheel and tire bearings can fail, increasing the risk of accidents.

There are multiple causes of wheel and tire failure, including:

  • Low or excess tire pressure
  • Over speeding often
  • Extreme heat that damages bearings and tires
  • Incapable brake discs

To avoid tire and wheel problems:

  • Regularly check the tire pressure.
  • If your wheels and tires are extremely hot, avoid hitting the road until they cool down.
  • Check the rating and speed limit of your tires and avoid overspeeding.
  • If your brakes aren’t working effectively, replace your brake discs.


Changing or replacing irreparable wheel bearings can cost up to $350 for each wheel.

Problem 5: Propane Leak Problems

Propane leakage in your RV is dangerous as it might cause a fire accident or explosion likely to end your life. Propane is highly flammable and can ignite fire quickly or endanger your lungs if it is leaked in a considerable amount.

Openings or cracks in the propane pipe can cause this leak. Other causes include:

  • Faulty Sealings
  • Fractured Propane Tank

To resolve propane leaking in your Bighorn motorhome:

  • Always look for the foul odor of leaking propane.
  • Regularly update and maintain your propane tank to ward off problems.
  • Inspect the propane pipelines using soapy, bubbly water to identify leaks.
  • If you notice propane leaking, turn off its system and replace the pipes immediately.


Replacing your propane tank will likely cost $100. You can DIY or hire a professional at a fee.

Problem 6: Engine Overheating

When the Bighorn RV’s engine becomes extremely hot, it will limit its performance and lead to costly damages. An engine problem is the last thing you will need on a road trip.

A malfunctioning cooling system or a clogged radiator always causes engine overheating.

To resolve engine overheating issues:

  • Check the coolant levels and ensure they are correct.
  • Make sure the cooling system doesn’t have air bubbles.

If these two solutions don’t cool the engine, take your recreational vehicle to a mechanic for professional investigations and repairs that follow manufacturer guidelines.


Extensive repairs for an overheating engine will be very costly. Replacing the head gasket, heater core, radiator, and water pump will cost $500 to $1500.

Problem 7: Fuel Line Blockages

A blocked fuel line will cause the RV to stall on the road or minimize its performance. This issue must be addressed because it can ruin your road trip.

The blockage in the fuel line is caused by debris due to neglect in regularly cleaning the fuel tank and line.


The best way to resolve this problem is by:

  • Changing the fuel filter regularly, especially when dirty.
  • If the fuel line is damaged or clogged beyond repair, replace it.
  • Cleaning the fuel tank will also help in keeping the fuel line clean.


The cost will depend on the extent of the problem and the parts that must be replaced. The price for new parts that might need replacement ranges from $10 to $530. Replacing the fuel pump will also cost $1000 to $1200.

Problem 8: Slide-Out Operation Problems

Slide-out malfunctions will limit your living space in most Bighorn RVs. This will make living in your RV inconvenient, especially if you are on an adventure with your family.

This issue is caused by damaged control units or faulty slide-out mechanisms.

To solve this problem:

  • Inspect the controls and motor for signs of wear and tear.
  • Make sure every cable is connected properly.
  • If the above two solutions fail, you might have to replace the whole slide-out mechanism.


Fixing the RV’s slide-out issues will cost around $500 to $5000

Problem 9: Furnace Problems

Furnace problems will make living in the RV unbearable, especially during winter. This issue will cause tubes and pipes to freeze due to extremely low temperatures.

To resolve the furnace problems:

  • Check if the ignitor has worn out.
  • Replace the filter.

Call an RV repair specialist for assistance if these solutions don’t deliver the desired results.


The cost of a new furnace for your RV ranges from $450 to $950.

Problem 10: Refrigerator Stopped Cooling

While on the road, you will need an optimally functioning refrigerator to keep your drinks cold and food fresh. This is one of the common Bighorn RV problems that require instant repairs.
