Camper Van Maintenance Guide: Keeping Your Van Adventure-Ready

Owning a campervan is an invitation to explore—but like any well-loved adventure rig, it needs regular care to keep performing at its best. We put this guide together to help you stay informed and empowered as you care for the conversion components in your van.

While this guide covers common upkeep tasks, it’s not exhaustive. Be sure to reference your owner’s manuals and check components routinely. This list also doesn’t cover standard vehicle maintenance like oil changes or tire rotations. Ultimately, the care and longevity of your van rest in your hands—but this guide is here to give you a strong foundation.

General Upkeep for Your Camper Van Conversion

Whether you live in your van full-time or use it for weekend getaways, a little routine care goes a long way. These upkeep tips help keep your systems running smoothly and extend the life of your van's key components.

Prevent Overheating in Hot Weather

• On days over 90°F, crack a window and turn on your vent fan to keep the air moving.

• Use insulated window coverings to block direct sunlight and help protect your interior components.

• If you're plugged into shore power and have an AC unit, set it to automatically turn on once the inside hits 90°F.

  
  

Fuel Levels for Diesel or Gas Heaters

• Keep your fuel tank at least ¼ full—many heaters won’t operate if fuel drops below this level.

  
  

Lithium Battery Care

• Try to keep your batteries above 20% charge. Dropping below that can trigger a system shutdown, which may require an external charger to get things running again.

• Repeated deep discharges can shorten the lifespan of your batteries over time.

  
  

Solar Panel Cleaning

• Clean regularly, especially if you’re traveling in dusty areas or parked under trees.

• Use warm water, automotive soap, and a soft cloth—avoid power washers or harsh cleaners.

Seasonal Camper Van Maintenance

Every few months, it’s smart to give your camper van a more thorough checkup. These seasonal tasks help you catch small issues before they become big problems—especially before or after long trips or extreme weather changes.

Keep in mind: not every van has the same setup. Depending on the components used in your build, some of these tasks may not apply, and there may be others you’ll want to add. Always follow the manufacturer’s maintenance guidelines for your specific gear.

Water Leak Check

• Use a hose to spray down windows, flares, fans, roof racks, and any other exterior installs.

• Do this after heavy storms too—it’s a good way to catch potential leaks early and make sure your sealants are holding up.

  
  

PEX Plumbing System Check (3 Steps)

1. Visual Check: Look over exposed PEX lines, fittings, the water pump, and accumulator for any signs of cracks or damage.

2. Leak Test: Run both hot and cold water and watch all joints and fittings.

3. Dryness Test: Dry the fittings with a cloth, wait a few minutes, and check again for moisture—any dampness may point to a slow leak.

   
   

Water System Maintenance

• Clean your fresh water tanks once or twice a year. We like using hypochlorous acid—a nontoxic, van-safe disinfectant.

• Sanitize your Pentair Shurflo water pump before and after storage (or anytime it's been opened). Refer to the manual for detailed steps.

• Replace your water filters about every 6 months or after 1,000 gallons—whichever comes first, depending on water quality and filter type.

Air Conditioner Maintenance

• Every 3 months, give both the evaporator and condenser a good cleaning. Dust and debris buildup can reduce performance and increase energy use.

• Always check your AC unit’s manual for brand-specific instructions.

Hydronic System Maintenance

• Check the glycol tank twice a year and top it off if levels are low.

Safety Equipment Checks

• Test CO and smoke alarms regularly, and swap out batteries as needed.

• Inspect your fire extinguisher—and if it’s expired (or close), go ahead and replace it.

  
  

Wood Surface Protection

• Reseal butcher block countertops and other wood surfaces using food-grade sealant or butcher block oil.

• How often? That depends on usage, exposure to moisture, visible wear, and the type of sealant—mineral oi or something more durable.

Final Thoughts

Staying on top of routine maintenance ensures your van stays safe, functional, and ready for the road ahead. A little care goes a long way toward avoiding costly repairs—and keeps your rig ready for wherever the next trail leads. For more van tips and resources, be sure to explore the rest of our blog.
