Sewer smell after driving

[ptomlinson]

I replaced the roof vents for the black and gray tanks as they were disintegrating from the sun. Ever since I replaced them the trailer smells like sewage after driving. I just went up top to make sure the vent pipes cleared the opening on both vents. Any advice ?
It never smelled before I changed the vents.
Question#2 ELECTRIC AWNING
when retracting the awning it is rolling close to the edge near the front of the trailer. The awning arm seems pretty wobbly but cannot seem to find a loose bolt any advice ?
Question #3 when flushing the black tank water is leaking onto the bathroom floor, from under the shower. I’ve opened the door in front of the shower pan ad cannot see any water coming in

We had that when we bought our FF x210. It had a factory installed sewer vent over the bathroom, similar to this:


We changed it to this 360 Siphon and all was good again. We still had a bathroom smell after someone used the bathroom (with solids).


Our new to us trailer came with this:

No smell. Ever. It's less than $10 more than the 360 siphon and well worth it.

I always leave some water in the bowl. It’s a barrier to gases coming up AND you can tell immediately when the seal is no longer good. As well i recently saw a video about cleaning the bowl and brush the seal area and down the tube to make sure there aren't any ‘clingons’ on the seal. And keeping the fan off when in use and when you drive
