I would ask about all the override systems, like how to get the slide in, and how to manually raise the gear if it is hydraulic, if it has a toung jack that is Electric, ask about the sheer pin, the bypass valve on the hot water system, and what to do if the awing goes out and not back, what is the manual retraction procedure. tank drain valves. And yes, make a video with your phone, and then make a hard copy. Might as well get a 4" 3 ring binder with 25 divider tabs and heavy duty plastic sheet protectors you can separate your manuals into them, make a index in the front of the binder. Believe me, it makes a difference when you can find the manual on stuff in your rv.
AND, look up your TT tires online, You may want to invest some better tires. Make sure everything is to your satisfaction, once you pull it out the yard, you own it, and your no longer their best friend.
These are the words I wish someone would have told me when I bought my first new rv.
Congrats on your TT, and Enjoy camping.
