new to forum here, first post after acquiring a 2003 e350 7.3.

i drove the van back where i purchased, was raining the whole way, after i got back i was doing some electrical work of adding additional rear outlets, i noticed under the driver's side floor covering some significant moisture.
Is there a problem with these vans of road moisture infiltrating around the doghouse?
Its been too cold here recently to do a full investigation.

 

I don't recall seeing the dog house as an issue (how would water get up there?), but windshield leaks are common (and would end up at floor level).
