Sewer vent smell - need advice
I am having an issue with sewer odors in my trailer. They seem the strongest around the toilet. I've done some research on here and I think I've narrowed it down to the rooftop vent for the black tank...

I've had the black tank pretty darn close to full and nothing out of the ordinary. I'm not sure I'm 100% on what you mean by a burp. I'm taking it as gases escaping from the toilet opening when flushing. When I flush it does get smelly but it doesn't make an audible sound!
YES............tank venting up thru toilet because vent line (if slipped down into tank) would be blocked and as you flushed the air/gases in black tank would have to come up out of toilet.
It does make an audible sound when that happens......and can spray back.
So it sounds like a 'craftsmanship' install......vent line cut to short. Should be at or above roof line and sealed from 'attic' area of roof.
