I was a huge fan of the A&E manual awnings for years till I bought their Step 1 or 1 Step or whatever they called it. It was only on the market a short time (couple of months) because it was a piece of junk. They should have all been recalled and replaced. That soured me on A&E - now called Dometic.
Our Trek came with a Carefree power awning and I love it! The first time I put the awning out, it went straight out. Knowing that wouldn't work, I adjusted both arms for maximum slant and it's been like that ever since. No other adjustments have been necessary - it stays at maximum slant all the time. There is NO POSSIBLE WAY for rain to ever pond on this awning.
If wind comes up, I push the button to put it away. I don't recommend leaving your RV with the awning extended. I recently purchased the remote control/wind sensor to upgrade it so that it will retract if winds come up and I'm not around plus it adds the feature that lets me sit on my can and use my phone to extend/retract the awning - less than $100.
I'll never, ever go back to Dometic awnings. I can't believe you have to fiddle with their awnings every time you put it out to get a decent slant on it. Pure non-sense! My advice would be to the OP would be to have your awning upgrade to Carefree hardware keeping only the fabric.
