If I replace my power awning, it will be with a manual one. Let me explain why:
The power awning is nice for the reasons you state, but it is fixed there. It goes out, it goes in. Period.
There is no provision for tilting it. I wasn't paying attention one rainy day and it filled up with water. I tried to retract it to shed the water. No sale on that one. I stood there in my rear doorway with a broom, trying to push up to dump the water. The nitrogen cylinder let go and down it came, into the open door, flooding the whole back of my TT. 4 letter word. Maybe 2 or 3 of those.
There is no provision to raise or lower it at the front either.
Personal preference, yes it's nice to push a button but I will take the old style manual any day.
Maybe some of the newer ones offer tilt, I don't know. To me, tilt is a mandatory feature.
