I had to use some sealant on my the front of my Axis windshield as well. I didnt want to hassel with my local Camping World and it took care of the leak just fine.
I did remove the "Buttons" on my bulk head. They are plastic and pop on and off pretty easy. Use a flat blade screw driver and pop off. It will reveil a philips head screws. I took mine down and installed a ton of heat and sound insulation in it. It helped some not as dramatic as I hoped it would be.
Check to see if your clearance lights are leaking into this area.
You should be able to open it up and let it air dry for a few days if it is wet inside (I dont think mine would get wet unless its the clearance lights leaking - but its been a year or more since I opened it up).
Not sure if you would see any damage once dry. It might show water stains on the wood inside but once you close it up you wont see it.
Let us know what you find and how you fixed it so others can learn.
