Got my LQ trailer ready for my first outing in early April, and discovered a wet area under the couch, where the water intake, water pump, hot water heater, and most of the fresh water tank reside. Knew the trailer was due to have the roof seams recaulked so just assumed that was where the leak was coming from. Thought we had all the potential leaking seams recaulked but continued to have moisture. Sometimes just damp, sometimes standing water. I live in Western WA and it has been a wet spring so it was tough to correlate the moisture with rain - its been raining constantly for about 2 months. Thought maybe the water tank was sweating, it had about 10 gallons in the tank all winter. Drained it, and have had no more moisture issues. Of course, one more potential roof leak was recaulked the same day. I am skeptical that the tank sweating was the cause of the moisture as at one point after a particularly heavy rain there was a puddle, but my husband is convinced it was the tank sweating. Anyone ever experienced this?

I should clarify that all water fittings checked out ok, none of the plumbing was leaking. At one point I thought it was the window above the couch leaking as I would swear I could see moisture coming from behind the end of the LQ interior wall (at the floor, under the couch) directly in line with the edge of the window.

I don't think the small amount of moisture from a sweating tank would produce standing water. "After the tank was drained, no more moisture issues" would normally indicate the tank or fittings are leaking. But you indicated an external trailer leak was fixed at the same time, so it could be either.
With the tank drained and rain, do you have water puddling on the floor? If no rain is forecast, hit that side of the trailer with a hose and check for leaks. If none is present, refill the tank and see if a leak then develops.
