Maintenance Tips

How to Prep Your RV Before It Goes into Storage

August 18, 2026

Storing an RV is not complicated, but the details matter. The units that come out of storage in great shape are almost always the ones that went in prepared. Here is the routine we recommend to customers at Highway 126 RV Storage before they park for the season.

Start With Water

Water left in the lines is the single most common source of expensive off-season damage. Drain the fresh water tank, the grey and black tanks, and the water heater, then run the pump briefly to clear what is left. If you are storing through a cold stretch, add RV antifreeze to the lines.

Leave the drain valves open so nothing collects while the RV sits.

Then Power

Disconnect the house batteries or pull the battery disconnect. A battery that sits connected will slowly drain itself flat and may not come back. If you can, top the charge up every couple of months.

Seal It Against Pests and Moisture

Empty the pantry completely — even sealed snacks attract rodents. Wipe down the fridge, prop the door open, and drop moisture absorbers in the coach and any closed cabinets. Close the roof vents but leave a vent cover cracked if you have one, so air still moves.

  • Remove all food, including canned goods
  • Prop the refrigerator and freezer doors open
  • Place moisture absorbers in the coach and closets
  • Check that all windows and roof vents are latched

Finish Outside

Wash the exterior before it sits. Bug splatter and tree sap bake into the finish over months of California sun and become far harder to remove later. Retract the awning fully, cover the tires if you have covers, and check that the slide seals are clean and dry before you bring the room in.

If any of that sounds like more of a Saturday than you have, we can wash and detail your RV for you while it is here. Call (805) 804-2599 and we will get it on the schedule.
