I just installed the free fix from Dometic on my electric awning. This is the fix so you can let one side down during rain so it can drain off. The kit was very easy to install the instructions are very easy to read. You do need two people to install as you have to hold up the awning while replacing the lower leg on the non electric leg of the awning. Now the awning works just like a manual one.
Great fix too bad they couldn't have done this in the beginning.
