The Great Thaw: How to Prep Your RV for Summer

Published on Apr 28, 2026 Blog Image

Winter is finally behind us, and the great thaw has begun. The snow is melting, the sun is shining, and your RV is calling you back to the open road. But before you pack up and head out for summer adventures, it’s important to give your RV some care and attention. Months of cold weather can leave behind hidden wear, frozen systems, or small issues that need fixing before you travel.

Step 1: Wake Up Your RV After Winter

Your RV has been resting through the cold months, so start with a gentle wake‑up.

  • Inspect the exterior: Walk around your RV and look for cracks in caulking, faded paint, or damage from ice and snow. Pay close attention to the roof and seals — winter moisture can sneak in.
  • Check for pests: Look for droppings, nests, or chewed wires.
  • Air it out: Open windows and doors to let fresh air in.

Pro Tip: A quick exterior check now can save you from costly leaks or repairs later.

Step 2: De‑Winterize Your Plumbing

If you winterized your RV, it’s time to reverse the process.

  • Flush the system: Run clean water through all faucets, showers, and toilets until the water runs clear. Keep the water heater in bypass mode.
  • Check for leaks: Inspect under sinks and around fittings.
  • Sanitize the fresh water tank: Use a drinking‑water‑safe freshener product.
  • Test the water pump: Ensure it runs smoothly and builds pressure.

Step 3: Protect Your Batteries

  • Remove batteries before winter: Store them in a warm, dry place and keep them charged.
  • Inspect connections: Clean corrosion and tighten cables.
  • Check voltage: A healthy battery reads around 12.6 volts.
  • Replace if needed: RV batteries last 3–5 years.
  • Test appliances: Run lights, fans, and outlets.

Step 4: Inspect Tires and Brakes

  • Check tire pressure: Inflate to the manufacturer’s recommended PSI.
  • Look for cracks or bulges: Replace damaged tires.
  • Check tread depth: Replace worn tires.
  • Test brakes: Listen for squeaks or grinding.

Pro Tip: Tires expire after 10 years — even with good tread.

Step 5: Test Propane and Safety Systems

  • Inspect tanks: Ensure they’re full and secure.
  • Check lines and regulators: Use soapy water to detect leaks.
  • Test appliances: Light burners, run furnace, check fridge.
  • Check detectors: Test smoke, CO, and propane alarms.

Pro Tip: LPG tanks expire after 10 years; alarms should be replaced every 5.

Step 6: Clean and Refresh the Interior

  • Vacuum and dust: Clean floors, vents, and corners.
  • Wash fabrics: Bedding, curtains, cushions.
  • Disinfect surfaces: Counters, sinks, bathrooms.
  • Check storage areas: Ensure they’re dry and odor‑free.

Pro Tip: A clean RV helps you spot leaks or mold early.

Step 7: Service the Engine and Generator (Motorized RVs)

  • Check fluids: Oil, coolant, brake fluid, transmission fluid.
  • Inspect belts and hoses: Replace cracked or worn parts.
  • Test the generator: Run under load for 30 minutes.
  • Schedule maintenance: If it’s been a year, book service.

Step 8: Restock Supplies

  • Kitchen gear: Pots, pans, utensils, RV‑friendly cookware.
  • Outdoor gear: Chairs, mats, grills, lanterns.
  • Safety gear: First aid kit, fire extinguisher, roadside kit.
  • Entertainment: Games, books, outdoor toys.
