What's Next in RV Prep?

My 'Slightly Used' RV

After it set in that I actually own this huge vehicle, I thought it needed some preparation. Although I wanted to get the stereo done, I started with a few other things.

I just returned from Target with some new bedding. The RV mattress was rather hard so I figured that a backache was not a good thing when I'm driving. I'll also need some type of pillow for my back since the seat does not adjust. It's actually rather funny. If I sit back, I feel like I need a beer belly and a beer in my hand.  There's so much room in the wrong ways!

I examined the stepping stools because yesterday I scraped my right knee and pinched my left leg behind the knee. Getting in and out of this RV is quite a challenge. Should I post my bruises so far?

Tomorrow I'm taking the RV in to get serviced. Hopefully the starting issue isn't that serious. I hesitated to buy any emergency items until I knew more about what I needed.
