We ordered an awning recently from ZipDee to replace the one on the living room slide (as you said the PO ripped the old one off).  The awning we chose extends out over the window and shades the window.  It works GREAT and keeps the limbs, leaves, rain off the top of the slide room - your slide room will probably leak like ours did without the awning if it's an HWH.  Read our posts about the slide room...  You will learn to just start the engine and merge the batteries when you are running the slide rooms in/out.  
As far as the bay door keys go:  do you have the electric solenoid locks (you don't need no stinking keys).  Our switch for ALL the bay doors is just inside the entry door on a panel.  I am in the process of replacing some of my solenoids but it is so worth it not to have to mess with keys!

We took ours to a locksmith when we first got it to get the safe opened & get a key made for it.  They made keys for bay doors at the same time.  Was pretty reasonable price wise.  After that I bought all new locks keyed alike and installed them myself when I was replacing faulty lock solenoids. Had to do some tial & error to get solenoid & key to both work together.  Also I got used solenoids from a wrecking yard and had some extensions welded on to get length right.  After all this I saw on here where Gurus had bought brand new solenoids on line for almost as cheap.
