2020 Toyota Tundra — footwell gets wet only after heavy rain

WeekendRoadie414Community StarterSep 13, 20252020 Toyota Tundra SR5Las Vegas
2020 Toyota Tundra SR5, about 99,000 miles. The car stays dry in normal rain but after a long storm one front footwell gets damp. Door seal looks okay. What drain/seam tests would you do before tearing the interior apart? I would rather test this logically than replace parts. I am trying not to assume the first explanation I see online.

Owner notes beat generic advice here. On the 2020 Toyota Tundra in Las Vegas, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “footwell gets wet only after heavy rain,” that was the fork that mattered for me. Time, temperature, and whether it's in gear are the notes that actually help a shop. That's my plan before I call anyone.

Don't overfit one forum story to your car. If it still isn't clear on the 2020 Toyota Tundra, a specialist hour can be cheaper than another round of parts. I'd do that before spending real money. Learned this the expensive way on a previous car. I'm keeping receipts and dates in one folder.
