Flies
We're having a problem with flies i.e. fruit and sewer flies. Can't seem to get rid of them in our travel trailer. We've flushed and cleaned out the grey water pipes/holding tanks and all other drains...

You did a lot of stuff that ought to work but the water in the sewer line won't help. The larvae came up through the water in my shower trap and then turned into flies. As flies they may also be able to get into the tanks via the roof vent.
I know the larvae travel through water. My hope is that the ones that do get that far won't come out on the RV side and get in when I open the valves to dump. Probably meaningless, but can't do any harm. I zip-tied a bit of screening to the roof vent after my first run in with these guys.
Sewer gnats are NOT fruit flies. Putting out wine or bananas is a pretty good way to attract fruit flies IN ADDITION TO the sewer gnats. The sewer gnats will ignore it.
