I have a 2015 high country that I am starting to have a wet floor on the table side slide out while driving in rain /wet roads. The area that gets wet is the carpeting that is covered by the slide out when the slide out is in. My model does come with a rubber splash guard on that side . Can anyone offer any suggestions as to how to fix this. We have owned this rig since it was new and have not had this problem until recently.
Check the silicone sealer at the bottom of the sidewall and the skirting (J panel)
If That moulding isn't sealed it will wick inside to your carpet. Also check the Eternabond tape where the slide flange is screwed to the slide roof. Mine was rubbed through over the screws. THAT will definitely get your carpet wet!
If that's not it, check the seals around nearby windows.

My 2014 305RL leaked badly the day we picked it up and drove 250 miles through a big rain storm. Leak in same area you mentioned,living room slide. Dryed out the next day with a box fan and did not have a leak while set-up for the next few days in heavy rain.. Driving home about 400 miles in rain caused a leak that wet the whole length of the slide for about 8 inches of the carpet edge. Back to dealer. After 3 -4 weeks of communicating with Montana to get OK to fix, it took less than 1 hour to fix as one area of the bottom the length of the slide had not been sealed at the factory. Dealer RV Connections Panama City stayed with the communication ordeal with pictures, letters, etc.and did a good job with the repair. Leaks can come from down below not always from above.
Our slide leaking problems started with the front end window of the large curb side slide. Turned out it was leaking through a paper thin gap in the sealant between the window flange and the wall surface. I caulked the entire perimeter with silicone and itís never leaked since. Then we had the window of the bedroom slide leak. It was the same problem and fixed it the same way. The last leak was the rear end window of the large curb side slide. This time, I not only caulked that window, but all the rest of the windows, and havenít had a leak since. I know the Ďproperí way should be removing the window and using new putty tape, but if it failed once, I would expect it to eventually leak again, so caulking with silicone works.
