Car/Truck Maintenance Checklist Before a Long Road Trip

Whether you're chasing sunsets along the coast or winding through the mountains, a road trip is one of the best ways to explore in your Four Wheel Camper. If you’re new to these long-awaited trips and are nervous about hitting the road, we get it! I think everyone in our community remembers the nerves of their first big trip. 

We’ve previously written an entire packing list for camping, but this time we’re focusing a bit more on the mechanics. Before you pack the snacks and queue up your favorite playlists, there’s one important step you shouldn’t skip—making sure your vehicle is road trip ready! 

Here is our go-to truck maintenance checklist before taking off on your big trip: 

Car/Truck Maintenance Checklist Before a Long Road Trip

1. Check Your Oil and Fluids

Before hitting the road, check the levels and condition of the following fluids:

• Engine oil – If it’s low or due for a change, get it serviced.
  
• Coolant – Crucial for preventing your engine from overheating.
  
• Brake fluid – Low levels can affect your stopping power.
  
• Transmission fluid – Helps keep gear shifts smooth.
  
• Windshield washer fluid – You’ll thank yourself when bugs and dirt start piling up.
  

2. Inspect Tires (Including the Spare)

Tires are your only contact with the road—make sure they’re in top shape:

• Tread depth – Worn tires can be dangerous, especially in rain.
  
• Tire pressure – Inflate to the manufacturer’s recommended PSI (found in the door jamb or owner’s manual).
  
• Look for cracks, bulges, or punctures – Replace tires if you notice damage.
  
• Check the spare tire – Ensure it's inflated and the jack/tools are accessible.
  

3. Test the Battery

A weak battery can leave you stranded in the worst places. Before you go:

• Check for corrosion on terminals and clean if needed.
  
• Ensure the battery is secure in its mount.
  
• If your battery is older than 3 years, consider having it tested or replaced.
  

4. Examine Brakes

Your brakes are vital to your safety. It is never a bad idea to get your brakes checked by a mechanic before leaving. In addition, watch out for these signs that attention is needed on your brakes: 

• Squeaking or grinding sounds
  
• Vibration when braking
  
• A soft or spongy brake pedal
  

5. Test All Lights

Make sure all exterior and interior lights are working:

• Headlights (low and high beams)
  
• Brake lights
  
• Turn signals
  
• Hazard lights
  
• Interior dome lights
  

6. Wipers and Windshield

A clean, streak-free windshield is key for visibility:

• Inspect wiper blades for wear or splitting—replace if needed.
  
• Top off windshield washer fluid.
  
• Check for windshield cracks that may worsen over time.
  

7. Top Off Emergency Supplies

Your car should always have a roadside emergency kit, especially on a long trip. Include:

• Jumper cables
  
• Flashlight with batteries or rechargeable headlamps
  
• First-aid kit
  
• Tire repair kit or sealant
  
• Plenty of water & snacks
  
• Reflective triangles or flares
  

8. Inspect Belts and Hoses

Pop the hood and check:

• Belts for fraying, cracking, or glazing
  
• Hoses for leaks, bulges, or stiffness
  

If you’re not sure what to look for, a mechanic can do a quick inspection.

9. Review Your Insurance and Registration

Double-check that your:

• Vehicle registration is up-to-date and in your glovebox
  
• Insurance card is accessible via app or in your car
  
• Roadside assistance info (if you have it) is saved in your phone
  

Additional Maintenance Checks For Your Four Wheel Camper 

Once you have your truck maintenance checklist completed, it’s time to shift gears to your truck camper! Before you set out, don’t forget to inspect the camper itself:

• Check the roof latches and make sure they secure properly.
• If your truck camper is bolted to your bed, make sure all bolts are tight and secure. If you recently had your truck camper installed, the bolts will settle and need to be tightened again after the first couple of trips. 
• Flush and sanitize the freshwater tank if it’s been sitting.
• Ensure the battery system is charged and holding power. In addition, make sure you have enough battery power for your needs. 
• Verify that the water pump and plumbing are functioning without leaks.
• Check all gear attached to exterior gear tracks to ensure they are secure.
