Required Items for New Travel Trailer?

Have a great trip.  I have found if I can fix little things it's way faster than waiting on a dealer to get around to it, too many horror stories with units tied up months.  As long as it's not some expensive part I just don't worry as having it available is more important than a few dollars.  Major repairs you have little choice unless it's under a manufactures warranty Norcold, Cleman, Suburban, etc then you can go to them or the dealer.  I have found the manufacture faster in most cases. 

Excellent, thanks for the update. That's the way to do it- drop it at the dealer, let them determine what's needed then take it back and use it. Bins are the way to go. Mine are stacked in the order used when setting up. Congratulations on a successful first trip.

If my wife was making up this list, she would include an Instant Pot, and a air fryer.
She has put together many a meal in the instant pot, we've gone out, and come back to dinner done.
Air fryer, is just so much easier to clean up and fast as well.

Wow, we just purchased a travel trailer and I had no idea what I didn't know. This is really great information! We have the essentials already, but I love the suggestions about camping in the driveway a couple times to get the feel of things. We are fortunate in that we live in a rural area and have well and septic, so we have our own dumping station! Thanks to all the contributors here. I'm sure we'll have more questions as we go along.

We're quickly getting to that point... My wife enjoyed shopping for new dishes / utensils / etc that are just for the camper.

Gotta figure that into the cost of buying an RV, lol!

Posting without reading ahead.

1.  Get a =good= hose kit, like Rhino, with swivels.  Also, make sure you have several 10' sections, as some CGs have weird setups.  I've seen where many parks are now requiring a hose support (Slunky, or the like) and an elbow, though an elbow is a no-brainer.
2.  The Progressive Industries units are excellent.  They have both portables and hardwired.  If you do take a surge, they are rebuildable for a reasonable price.  Protects from under/over voltage, as well as wiring problems (mostly for 50a service).
3.  Get an =adjustable= pressure regulator with gauge.
4.  Get some "lego" blocks, too.  Also, carry some wood to put under the stabilizers.  The shorter they are, the more stable.
5.  Get 2 25' white water hoses because, as I said earlier, some CGs simply have weird setups.  You don't need to use both, but having the extra doesn't take up much room and can save your bacon in a pinch.  Also, use a =separate= hose for general use, like the black tank flush.  A 25' hose should be good, as you can simply use the water hose on the faucet and the "general" hose on the end of that, if needed.
6.  Propane tank gauges are notoriously inaccurate and the ones that work best are usually expensive.  If you need to, boil some water, pour it down the side of the tank and check the temp difference between the top and bottom.  Same as you'd do with an outside water tank; run your hand down the side and when you hit the cool portion, that's the level.
7.  I've never felt the need for a filter, but if you camp where there's crappy water, then go for it.  Some people even use a portable softener.
8.  Check out Harbor Freight tool kits.  Can get some really nice ones for pretty cheap.  They have them from 100 pieces up to > 300 pieces.  I'd also add a dedicated basic electric kit with fuses, connectors of various kinds, tape and a =good= set of strippers/crimpers, like a Klein tool.
9.  Tank chems are a real choice.  To some people, they're worse than the sewer smell, so they don't use them.  Just try a few different ones and get what you like.  I was camping last weekend and put one in, and there was literally zero smell, either from the sewage or from the chemical.  Can't remember the name, off hand, but I'm pretty sure I got it at WallyWorld.  Orange stuff.
10.  Don't bother with "RV TP", just use the regular stuff you normally use.  Just use lots of water.  If you want to help keep your tank clean, use the GEO Method.  Mix some Calgon bath powder or Borax with some =original= Dawn dish soap and dose the tank each time you use it.  The water treatment softens the water and the Dawn helps break down other stuff.  Can also use this in the grey tank, as they can get nasty with food particles.  (I wish they'd put tank flushes on the grey tanks, too.)  When we boondock, the last thing I do is take one of my spare blue cube water totes and dump the whole thing in the toilet (assuming there's room for it).  My tank gets good 'n clean going down the road from our annual campout with all the water I put in it.  :-)

Other things to think about adding:
1 or 2 extra fire extinguishers.  That little pissant one that has to be included =might= get you out, but don't bet your life on it.
Digital battery voltage readout.
110v indicator.  Just an inexpensive one that you can plug into a recep in the kitchen or bath.
With only 20 gal, fresh water, get some of the "blue cubes" to carry with you.
You might want to put together some dedicated "camp boxes" to carry some of these in the tow vehicle since your cargo capacity is so limited.  Can store inside the trailer when you're not using it.
2nd battery.
Extra propane bottles.
As the rig is solar prepped, add a solar panel.
