Tip: Monitor battery levels and conserve 12V power when dry camping.

Plumbing Systems

Complete water and waste systems for self-contained travel.

  1. Fresh water system: Fill tank through designated fill port; use water pump or city water connection.
  2. Water heater: Operate on propane or electricity (when available); drain when winterizing.
  3. Gray water system: Collects sink and shower water; drain at approved dump stations.
  4. Black water system: Holds toilet waste; use plenty of water and proper chemicals.
  5. Winterizing: Use RV antifreeze in all water lines when storing in freezing temperatures.

WARNING! Never leave black tank valve open - always dump when nearly full.

Winterization

Proper preparation protects your motorhome during cold weather storage.

  2. LP gas: Turn off tanks at valves; run appliances until fuel lines are empty.
  3. Batteries: Disconnect and store in cool, dry place; maintain charge.
  4. Exterior: Clean and wax; check all seals and caulking.
