Inside the camper, I could not detect any leaks.
Outside the camper, I saw the grey tank and it looked like the leaks were happening above it having the water fall on the side of the tank. But I can't say for sure which connection is causing this.
I called General RV's service. While the lady wasn't a tech she did mention it could have been the overflow on this tank because of the level.
Is there a way to test this tank while at home before going out again?
Oh yes, my only overflow situation was with my black tank. That was ugly but at least it didn't back up into the trailer. So maybe a leaky top fitting is good thing! (For me, not the neighbours ...)
If you know the tank size and you've the trailer level in your driveway, try filling it up with known quantity of water. See when it overflows. I wouldn't worry if it's a leaky top fitting. Just be cautious about leveling the trailer and over-filling in the future.
