There is much you can learn and, in fact, do to make this a better experience over all.
This all starts at the dealership when picking up your new TT.
First, tell the salesperson that you will require a FULL lengthy PDI (Pre-Delivery Inspection). This means you will spend two or more hours going through the TT examining every system and you will expect the dealer to demonstrate (teaching you and proving to you) that everything is working properly. Many, too many, dealers rush this part, or schedule your pickup too late in the day. Let them know you will not accept this kind of PDI.
You will do the PDI before you sign and close on the RV. If your TT has problems during the PDI don’t accept the TT anyway with a promise that they’ll fix it later. Too many have found this to be a problem later. Once you’ve paid for the TT the dealer’s desire to make good on things dwindles rapidly.
Be aware that, just like buying a car, at the Closing the F&I person will try to sell you all manor of worthless overpriced “must have” options. Their job is to maximize profit for the dealer. Chief amount these things will be a “extended warranty.”
First, you should consider long and hard if you want one. Unlike motorhomes, travel trailers just don’t have that many expensive items that are even covered by such a warranty. Even then you need to know two things: first, it’s not a warranty it’s breakdown insurance is designed to actually pay for as few, if any, breakdowns as possibly. Next the dealership is the worst place to buy one of these contracts. They buy them cheap and sell them at a huge markup. They make a fortune on these and even if they “discount” it to entice you to buy you will be overpaying.
If you want an extended service contract you can buy one later from an independent seller later for much less money. The dealer will likely tell you that everyone buys a warranty and theirs is the best. Neither of which are true.
Best of luck, and as Richard said, it’s really best if you leave the dealer and go to a campground as close as possible to the dealer for a 1 to 3 -day stay in your new TT. This will show you three things - what works and what’s not working, what you don’t know about the operation of your RV and lastly what you need to purchase to augment your new travel trailer.
