Add-ons to new trailer - Suggestions

I've owned our first travel trailer since 2008, and we've used her a lot; but I'm getting ready to pull the trigger on a new coach. It's been a while since I've done this, so I am looking for suggestions on what to have added to her. It's a new Keystone Bullet (non-Premier), and it has a lot of standard features such as power tongue jack, black tank flush, power awning, cable/sat, hot water bypass, etc.

Here are some things that I'm considering on top of that, but I'm sure I'm forgetting some stuff:

Battery disconnect switch
Max-Air vent covers
Hitch work
LCD TV mount in bunk area???
Curved shower curtain rod???
