Welcome to Airstreaming! There are as many ways of celebrating a new Airstream as there are different Airstreams and their owners.
Our first trip was about 200 miles, to a gathering on a friend's place in hilly wilderness. We took our "Tin Pickle" down a steep (12+%), narrow, twisty dirt private road with cut on one side and steep drop on the other. Parking was no easier. We found a spot sideways to the slope, but the only way we could level the trailer was to park the downhill wheels on a rock, supported by a couple of boards.
We'd done enough work on the trailer to have new axles, brakes and lights. The fresh water tank and pump still worked, as did the stove. But for the rest, we had an airbed, an ice chest and a nearby privy. After that, anything was easy!
(We've since redone the entire interior and our camping is downright cushy now.)
So if anything goes remotely amiss, just raise another glass of wine and say "It could be worse. We could be on the side of a hill, and with no amenities." Enjoy!
