Congrats on the new hobby!
Yes, there's a pretty big learning curve for people who've never RV'd. And you'll see many different variations on campsites so it's good to always have extra sewers hoses and extra fresh water hoses to compensate. (I've even seen camp sites with all the hook-ups on the RIGHT side!!)
Most of us spend our long and lonely winter months buying stuff for our campers...it helps minimize the cabin fever a bit!
Concerning your awning, you really don't want to put it out when it's raining hard or it's windy...you're just asking for trouble, IMHO. (I only put mine out in the rain when I want to BBQ underneath it...but it goes back up when I'm done.)
