ON my 2007 Cruiser, it would be pretty straight-forward. Disconnect power at the source, secure the water and gas. Disconnect wiring, waterlines and gas line from the water heater inside of the rig. Remove all the screws from the outside of the rig and slide the unit out. I have thought about this since my unit is getting older but have never done it. Once complete, do a quick write-up and tell us how it went.
