Sounds like funk mineral deposits collecting in the hot water tank. Strange on such a young unit IMO. My mom's safari was so bad the entire coach smelled like sulfur and for months and months we thought it was somehow related to the holding tanks venting into the unit. When I finally traced it to the hot water tank, I drained it and you would not believe the nasty, jelly-like crap that came out.

I filled it up with bleach water and let sit for a day and then flushed it out continuously with a garden hose.
