All good suggestions. I have checked the clamp load and I don't think that was it. One thing to note is that when we opened the door we saw the water before I raised the walls. We looked carefully at the folded walls and door at that time to see where the water might have come from before moving anything (comes from my engineering background to disturb nothing until fully investigated).
The folded walls were "bone dry" as well as the inside of the roof and top of the sink/stove cabinet. Once I folded up the walls we looked everywhere to see if any lower walls or the microwave cabinet was wet. All were dry except the floor starting in front of the refrigerator and running back toward the bed. The floor under the table and in the entryway were dry; it was only wet from the refrigerator to the cool cat.
While my wife dried that up I inspected the vents to see if that was the culprit.
Our towing setup has the front of the trailer slightly elevated from the truck hitch a degree or so because of the adjustment holes in the coupler. The bolt hole beneath the one I use causes the trailer to tilt down about 5 degrees and the one I used has it "almost" level with a small tilt up. My WDH can't compensate enough to level it in the lower hole. The WDH lets it tilt down about a degree when the chains aren't connected and it tilts up about a degree once the chains are secured. That means I really don't need the WDH but I already had it from my previous trailer and it stops sway so the slight tilt up is OK. A bubble level is still "in the lines" when I'm on level ground. The tilt is negligible however it would help explain why it starts at the middle of the refrigerator and runs backward.
No sign of water in the front compartment but some dampness was found on the wall between the exterior refrigerator compartment and the furnace towards the center of the trailer when viewed with the vent off. This makes me think it did come in through the lower vent since it was wet on the floor behind the refrigerator and on this wall at that corner. None of the refrigerator components were wet and the flame was still on so it had to be low on the vent when it came in.
My question is more what was done to prevent it by people who have seen this before or do I have to live with it.
Our previous trailer had a mysterious leak that only happened twice during two torrential rainstorms with high winds over a 16 year period. I never found the true source although I suspected the water heater vent taking on water. The irony is that both times it happened were during different years at the Amarillo KOA so we eventually decided the trailer didn't like that park
Never happened again. So maybe this trailer doesn't like Rapid City? LOL.
