Congratulations and welcome to the forum. As goodtruck stated above, spend alot of time opening every cabinet, drawers, turning on every faucet, light switches, run the slides and awning in/out many times, turn on tv, etc, etc, etc. Don't forgot the water pump. It will help you understand what's what on the coach but if a problem arises, how to get it corrected before it leaves the lot.
Enjoy and travel safely.
