Vent under sink cause of smelly trailer?
My trailer smells gross come summer time. Was gone 3 weeks and come home to that sewer smell. To me it smells like gray tank. Pretty sure my P traps are still filled with water. It must be the kit...

When was the AAV added to the standard?
I don't think my 1990 Winnebago has one.
No idea about RV timing , but reading some stuff I Googled, it looks like they came into use in Can/US about twenty years ago, but only started getting code approvals around 2008 give or take. Those limited use approvals have since been expanded allowing more in stick houses/apartment buildings than originally.
That could be why I never saw any in my 2003 5er. Of course "standards" and "guides" are not "codes" AFAIK. (RVs are not stick houses for all code things apparently)
