Welcome John! Nice looking rig.
The "pickup" process is known as a PDI and if you do a search on Google for PDI Checklist you will come up with tons of options.
Here are a couple of popular ones:

These will help, but the key is to "make" the dealer not rush you through and to go over everything - not just the obvious big things but EVERY TINY LITTLE THING.
They will want you to think that they've given the TT a full check out before you arrive. But that's almost never the case. They'll clean it. Maybe spend a little attention to the biggest things and that's it. It is common for dealers to do as little as possible before the sale in the hopes that you'll be long gone before noticing missing or defective items.
It's not like buying a car where everything works as soon as the car is delivered. In fact, it's not like buying a car at all. RVs frequently leave the factory with multiple problems and issues. The buyer is usually the final quality control person.
Be aware that the dealer will try to sell you all manor of useless things to boost his profit. They will tell you that you MUST buy this stuff and everybody does so - but it's not true at all. Things like extended warranties, paint protection, tire insurance, fabric protection, etc are on this list. Since you're getting a travel trailer you can ignore all of these "products."
Also, do not take possession until you've done the PDI and are confident that EVERYTHING is working and nothing is missing. Many times they try to rush you through and get you to accept delivery. They will of course tell you if you have any problems you can count on them to make it right. Unfortunately, it's routine that once you've accepted delivery and paid for the TT the dealer will develop amnesia and forget all about you and your problems.
The last bit of advice is the hardest to accept - be prepared to reject this TT and walk away if during the PDI you find problems or missing items. You probably won't need to do this, but you should be prepared to if needed.
PS. Don't skimp on the hitch - plan to pony up for a good strong weight distribution / Anti-sway hitch - don't buy the cheapest hitch they sell to keep the cost down. You'll end up buying a good hitch in the long run so research and be prepared to spend a couple extra hundred dollars for a good hitch.
