Any host owners have leaks ?

2018 host mammonth. I have water leaking in on both front lower conners of the side slides, doesn’t matter if slides are open or closed so I am thinking that eliminates the slide seals . Water drips between slide seal and the wall at the end of the inside seal , same on both sides so far have not found any suspicious chalking just wanted to ask here if any other host owners have this issue and maybe a resolution . If you have never taken the carpet covered trim Pieces off , (good luck finding the screws,!!)you may not know you have a leak we found ours in a three day heavy rain as the carpet on those corners got wet . The bathroom side is just a corner pice the kitchen side actually covers the fresh water tank fill hose and some wiring for the awning. Getting a moisture meter to see if I can track down the source of the leak . I love this camper but these leaks are really annoying I have a dehumidifier running to try to prevent damage .
Thanks for any help
