What to Look for When Buying a Used Diesel Pusher RV

Purchasing a used diesel pusher RV can be a savvy way to get into the world of luxury motorhomes without paying the premium price of a brand-new model. However, it’s crucial to approach the buying process with a discerning eye. With these powerhouse rigs featuring complex systems and high upfront costs, knowing what to inspect can save you from future headaches. Here’s a comprehensive guide to help you make an informed decision.

Why Choose a Diesel Pusher?

Diesel pushers are renowned for their durability, power, and luxury features. The engine, located at the rear, provides a quieter cabin experience and exceptional towing capacity, making them ideal for long hauls. Additionally, their robust diesel engines often outlast gas counterparts, offering better fuel efficiency and performance.

Essential Factors to Inspect

1. Engine and Drivetrain Condition

The engine is the heart of a diesel pusher. Look for signs of wear, excessive smoke, or unusual noises during startup and operation. Request service records to ensure regular preventive maintenance and ask about recent repairs to components like the turbocharger, fuel injectors, and transmission.

2. Mileage and Usage

While diesel engines are built to last, high mileage still impacts longevity. Aim for a balance—too many miles could mean wear and tear, while too few might indicate the RV has been idle for extended periods, leading to issues like seized components or degraded seals.

3. Chassis and Frame

Inspect the chassis for rust, cracks, or damage. Pay close attention to areas near the axles, suspension, and welds. These elements bear the weight of the RV, and structural issues can compromise safety.

4. Suspension System

Diesel pushers typically use air suspension, which ensures a smooth ride. Check for leaks in the air system, damaged bags, or uneven leveling when parked. Faulty air suspension can lead to a bumpy ride and expensive repairs.

5. Electrical Systems

Test all electrical components, from interior lights and outlets to the inverter and generator. Ensure the batteries are in good condition and hold a charge. Faulty electrical systems can be costly to fix and disrupt your travel plans.

6. Plumbing and Tanks

Inspect the plumbing for leaks, cracks, or signs of wear. Test the water pump, faucets, and water heater. Verify that the freshwater, greywater, and blackwater tanks are in good shape with no signs of damage or improper maintenance.

7. HVAC Systems

Diesel pushers often feature multiple air conditioning units and furnaces to maintain comfort. Test both heating and cooling systems to ensure they’re functioning efficiently.

8. Tires and Brakes

Check the tires for uneven wear, dry rot, or low tread depth. Tires on diesel pushers are costly, so budgeting for replacements is essential if they’re worn. Inspect the air brake system for responsiveness and leaks.

Red Flags to Avoid

• Incomplete Service Records: If the seller cannot provide maintenance history, it may indicate neglect.
• Water Damage: Stains, soft spots in the floor or ceiling, or a musty odor suggest water damage, which can be costly to repair.
• Delamination: Bubbles or ripples in the exterior walls can indicate moisture intrusion and structural damage.
• Persistent Dashboard Warnings: Any engine codes or warning lights that remain active after startup need further investigation.

Questions to Ask the Seller

1. Why are you selling the RV?
2. Have there been any major repairs?
3. Is the title clean, or has the RV been salvaged?
4. What is the average fuel efficiency under load?
5. How old are the tires, and have they been replaced?
