Important: Always follow the storage recommendations in your Mars owner documentation and the manufacturer manuals for batteries, appliances, gas and water systems.

1) Choosing a storage location

  • Best option: Under cover (shed or carport) with good airflow.
  • Next best: Outdoors in a well-drained area using a suitable breathable caravan cover.

Avoid if possible:

  • Long-term storage under trees that drop sap, nuts or branches.
  • Areas prone to pooling water or constant dampness.
  • Fully sealed environments with no airflow (especially hot sheds).

2) Covers (outdoor / carport storage)

  • Use a breathable cover designed for caravans.
  • Fit it only when the van is clean and completely dry.
  • Secure it tightly so it doesn’t flap — flapping can rub corners and edges over time.
  • After windy weather, re-check straps and inspect rub points.

Covers help reduce UV exposure and dirt build-up, but they must still allow moisture to escape. For hot shed / long-term storage, follow the main guide linked above.

3) Ventilation & moisture control

  • If safe and secure, allow gentle airflow (e.g., a roof vent slightly open as weather allows).
  • Open internal doors (cupboards/pantry/bathroom) so air can move through the whole van.
  • Remove wet towels/mats and don’t store the van with damp gear inside.
  • Consider moisture absorbers in wardrobes/under-bed areas and check them regularly.

4) Quick storage prep

  • Wash exterior and allow it to fully dry.
  • Empty rubbish and remove food items.
  • Clean the fridge and store the door ajar if recommended by the manufacturer.
  • Turn gas bottles off at the bottle.
  • Do a quick walk-around to spot anything that needs attention before the next trip.

For long-term storage (or hot sheds): use the full guide and/or the checklist linked at the top of this article.

5) Periodic checks (even when it’s parked)

Even if the van isn’t moving, a quick monthly check helps you catch small issues early:

  • Check the cover (if used) hasn’t loosened or started rubbing.
  • Look for storm/branch damage and any signs of pests around wheels and underbody.
  • Open the van briefly (if possible) and check for unusual smells or visible moisture.

Summary: Store under cover where possible, use a breathable cover if needed, keep airflow happening, and check in occasionally.
