Air Conditioner Diagnosis & repair

In the scorching heat of Texas, maintaining your RV's air conditioning system is paramount for comfort, safety, and overall enjoyment of your travels. With temperatures often soaring well above 90 degrees Fahrenheit, a properly functioning AC unit can provide a much-needed respite from the relentless heat, allowing you to relax and recharge after a day of adventure. Moreover, in extreme heat conditions, prolonged exposure can lead to heat-related illnesses, making a functioning AC system not just a luxury but a necessity for your well-being. Regular maintenance ensures that your RV's AC operates efficiently, preventing breakdowns during crucial moments of your journey and potentially costly repairs. By keeping your AC in top condition, you not only enhance your travel experience but also ensure a comfortable and safe environment for you and your fellow travelers, even amidst the sweltering Texas heat.

Electrical Troubleshooting & Repair

Maintaining both the 120V and 12V electrical systems in an RV is paramount for ensuring a safe and comfortable journey. The 120V system powers appliances like air conditioners, microwaves, and TVs, providing essential comforts of home while on the road. Regular inspections and upkeep of this system prevent potential hazards such as electrical fires or short circuits. Similarly, the 12V system, powered by batteries, operates crucial components such as lights, water pumps, and refrigerators. Maintaining this system guarantees uninterrupted functionality, especially during off-grid adventures. Neglecting either system can lead to inconvenient breakdowns or, worse, safety hazards in remote locations. Thus, prioritizing the maintenance of both electrical systems is fundamental for a smooth and secure RV experience.

Roof Repair & Replacement

Repairing or replacing the roof of an RV is a crucial aspect of maintenance for any avid traveler or weekend adventurer. Over time, exposure to harsh weather conditions, UV rays, and general wear and tear can lead to leaks, cracks, or deterioration in the roof's integrity. When it comes to repair, identifying and sealing leaks promptly is essential to prevent further damage to the interior. Common repair techniques include patching holes, resealing seams, and addressing any water damage. However, in cases where the damage is extensive or the roof material has reached the end of its lifespan, a full replacement might be necessary. Replacing the RV roof involves stripping off the old material, inspecting the underlying structure for any damage, and then installing a new roof membrane or material, ensuring a watertight seal and durability for future adventures. Whether it's a minor repair or a complete replacement, maintaining the integrity of the RV roof ensures continued comfort and safety on the road.

Water Heater Maintenance & Repair

Maintaining your water heater is of paramount importance for several reasons. Firstly, regular maintenance ensures the efficient operation of the water heater, which directly impacts energy consumption and utility bills. A well-maintained water heater is less likely to develop issues such as leaks or corrosion, thus extending its lifespan and reducing the need for costly repairs or replacements. Additionally, proper maintenance helps maintain water quality by preventing the buildup of sediment and mineral deposits, which can affect the taste and quality of water. Moreover, neglecting water heater maintenance can pose safety risks, including the potential for explosions or gas leaks in the case of gas-powered heaters. Therefore, by scheduling routine inspections, flushing the tank periodically, and addressing any issues promptly, homeowners can ensure the reliability, safety, and efficiency of their water heating systems.

Leveling Systems & Slide Outs

Maintaining your RV leveling systems and slideouts is paramount for ensuring a safe and enjoyable journey on the road. Properly leveled RVs provide stability, preventing issues like swaying or tipping, which can lead to accidents. Additionally, maintaining slideouts ensures that they operate smoothly, preventing jams or malfunctions that could cause inconvenience or even damage to the RV. Regular inspections and maintenance of leveling systems and slideouts help detect any issues early on, allowing for timely repairs and preventing costly breakdowns during travel. By prioritizing maintenance, RV owners can enhance the longevity and reliability of their vehicles, ensuring each trip is as comfortable and worry-free as possible.


Maintaining your RV furnace is crucial for ensuring safe and efficient operation, especially during colder seasons when it's relied upon for heating. Regular maintenance begins with inspecting the furnace's exterior and interior components for any signs of damage or debris accumulation. Cleaning or replacing the air filter is essential to maintain proper airflow and prevent dust buildup, which can hinder performance. Additionally, inspecting the burner assembly, blower motor, and ductwork for any obstructions or wear is vital. Lubricating moving parts and tightening electrical connections can help prevent malfunctions and extend the furnace's lifespan. It's also important to check the exhaust vent for blockages and ensure carbon monoxide detectors are functioning correctly for safety. Regular professional inspections and servicing are recommended to address any potential issues before they escalate, ensuring your RV furnace operates reliably when needed.

Plumbing & Water Systems

RV plumbing repair and maintenance are essential tasks to ensure smooth operations and prevent potential water damage while on the road. Regularly inspecting and maintaining the plumbing system can help identify leaks, clogs, or other issues early on. Start by checking all connections for tightness and signs of corrosion. Replace worn-out seals and fittings as needed to prevent leaks. Clean out debris from drains and pipes to prevent clogs, and use RV-safe plumbing products to avoid damage to the system. Additionally, it's crucial to winterize the plumbing system before cold weather sets in to prevent freezing and bursting pipes. Performing these routine checks and maintenance tasks can help keep the RV's plumbing system in optimal condition, ensuring a hassle-free journey.

Our RV Parts

At Boss Bull Mobile RV Services we do our best to stock common items for RV repairs. However, with hundreds of RV manufacturers, sometimes the only way to get the right part is to order it specially.

Most of the time, manufacturers can provide these parts promptly. Because we stand behind our work, we only work with parts from authorized manufacturers. 

We do not install parts supplied by customers.Our ability to supply parts quickly may be limited by any supply chain issues or shortages. We will let you know if we are experiencing such delays.

What is your labor warranty?

For your peace of mind, every service comes with a 30-day no-fuss labor warranty. If something is wrong with the job, we'll make it right at no additional cost to you. The only exception is for parts that would have been incurred in the normal course of the repair.

How do you document the needed repairs?

To facilitate internal and external communication, our technicians use an app on their cell phones and tablets.

This allows us to address service needs and document work performed more efficiently. We use the app to take and upload photos as necessary.

You will be asked to provide a pre-work signature as well as a post-work signature in this app when you work with the team at Boss Bull Mobile RV Services.

Do you work with warranty or extended warranty companies?

We also offer warranty work through extended warranty companies and parts manufacturers.

Due to the Texas franchise law, we can't have financial transactions with companies that make RVs. Please remember that your warranty may not cover the entire repair. Therefore, you will be responsible for the uncovered portion.

This basically means that if you are under your first-year manufacturer warranty, we can assist you with those items, but payment would come from you and you could then seek reimbursement from the manufacturer.

Do you work with insurance claims?

We are happy to work with your insurance company. This requires an estimate from us. Our customer will cover the cost, and that cost is applied to your deductible.
