Hello & Welcome!
I am pretty new to RVing too. Thankfully my BF is not. When we purchased our RV, I was completely lost. So many switches for everything! I had to take notes to figure out how to use the digital thermostats, and finally the BF made new labels for all of the switches for me. Even then, I sometimes accidentally will cut off all house power... Oops!!
You're questions have already been answered, but I do highly recommend the driveway overnighter if you can! You'll learn so much just by play camping! Just hanging out in your rig, you'll learn a lot of cool tips and tricks!!
Good luck, and safe travels!
