On the sewer gas smell. Did you have any of the windows open to pull air from the exterior with the fan on. I have found ours is sealed pretty tight. Have the entry door slightly cracked and move a slide...it will push open or slam closed. Pretty tight.
The shower head will still leak. It's made to. Any rv replacement head will as well. Even our Oxygenics does this.
Hang in there with the pump. Our second trip it was much quieter. I don't think it's the pump as much as the mounting. I suppose yours is worst since it's under your bathroom, ours is under the hallway.
We also have rotochoks... they help, but I think we are going to get the JT stabilizers too.
Glad you enjoyed your trip.....and jealous of the dual pane windows and genny.
