We've had our 2008 Jayco Pop Up (model 1006) for a little over a year now and I thought about using the outside shower for the kids to rinse off after getting out of the lake. I'd like to use the hot water heater, but reading through the manual doesn't really explain how to use it. I'm assuming there is some sort of reserve that I can activate to use the hot water heater...and then I'm not really sure how to even light the how water heater. I've searched on YouTube for videos on how to do this, but have not found anything specific to my camper. Anyone familiar with how to do all this? Can you give me a quick run-down or a link to a video/tutorial?
