- Make sure the tire pressure is at the max pressure shown on the sidewall of the tire.
- Grease your wheel bearings if necessary. Official word is do this every year, with the few miles put on every year I usually go 2-3.
- Refill propane tank if necessary.
- Reinstall battery if you kept it elsewhere over the winter (storage outside on the tongue is fine and can actually extend the life of the battery as long as you charge it twice over the winter).
- Hook up your hose (white hose not necessary for this, but make sure you use a white hose in camp).
- Make sure the valve near the water pump, used to suck up antifreeze, is set properly.
- Pressurize the water system, then open each valve on the sink, shower and toilet one at a time until they run clear.
- Switch all 3 bypass valves opposite of how you kept them over the winter (during the summer the ones on the hot and cold lines should be parallel to the water line, and the one in the middle should be perpendicular).
- Add chemicals as necessary to the black tank, filling with several gallons of water.
- Check/replace the batteries in the smoke detector and carbon monoxide detector.
- Hook up the Bargman connector to your car and check all exterior lights.
If anyone thinks of additions I'll add them.
