I had a Glass company put a new window in and it continues to unseal it self.
It has unsealed it self three times. I personally used 3m Silicone sealant and when
it got cold here in Washington it fell out in little pieces. It wasn't safety Glass, Shound be and is it a contured glass just for the axis? Jim
Your problem is simple. You used silicone. Never use silicone on an rv. Nothing will stick to the area after it has been removed. Tell the glass company that you used silicone. They might have a solvent to clean the area prior to reinstalling your window. If you still have some silicone left over, walk, no run to your trash bin and get rid of it.
