Water on floor

-It was pouring rain, I mean really coming down with standing water on the highway so we drove slow.

-I wiped up the water as best I could with a couple towels after arriving and it continued to rain for the next 2 days.  We didn't see any water accumulation inside the pod during that time.  When we drove home it was only lightly raining and there was also no water accumulation inside.

At this point I am assuming that the water came up from the base of the pod but don't know how that would be possible.  Any ideas or other thoughts?  I love the pod size and maneuverability but have become so tired of continued problems at every outing (only 14 outings with 4 dealer visits for significant issues).  We have owned the pod for just over a year (2018 model) and have had multiple problems with water ingress (slide leak, rear spoiler leak which led to ceiling bubbles and an ongoing warranty debate with manufacturer).  Both slide leak and ceiling leak have been sealed recently by the dealer.  Please convince to keep the pod!  At the moment I think I got a lemon and need to move on to a different trailer.  How can a company expect a customer to deal with floor, ceiling, and slide leakage within 14 months of ownership?  What am I missing?  Thanks and cheers.

We purchased a 2010 171 last December.  The floor had a little softness but was frozen.  Once thawed out it was spongy.  Upon investigation by removing the linoleum, the entire floor was wet and the front area (dinette, in front of kitchen and bath to the front of bed) the subfloor was delaminated.  The flooring had held any water that had entered the Pod and where the greatest exposure occurred it held and damaged through both layers of the luan subfloor and styrofoam.  There were entry points throughout the Pod (hatch seals, shore power inlet, aging seals at the wall appliances and through points in the floor) but the most significant was the front seal where the roof attached to the floor.  Only three of the multiple screws attaching the trim were in contact with structure due to water intrusion, rot and short hardware.  Although the pod had little visible wear, the maintenance of the seals was not evident in addition it was difficult to determine how well it had come sealed from the factory.

The happy ending that after extensive work repairing and replacing portions of the subfloor and insulation, replacing 12" strip of luan in the front of the coach, Spray foam insulation replacing the soaked Fiberglass insulation and finishing the epoxy coated subfloor with waterproof vinyl planks and laminating a Front diamond plate rock guard, I have a camper that I love.  I am a newbie and have taken it out three times, the first being a 2700 mile nine day trek to the Great Smoky Mountains, and the 171 with several mods has worked out much better than my expectations.

I thought about the vents (especially when I was power-washing my Pod last week) but I think that the water would have to be shooting right at the vents in an almost upright direction to cause as much accumulation as you got.
