Well, we got our beautiful new Airstream home safe and sound.
The things we did right:
I videoed the entire tour
We practiced hitching and unhitching several times.
We practiced putting up and down the awning.
I folded down the beds.
I asked a lot of questions.
Things we didn't do right:
I guess I should have asked a few more vital questions.
I didn't test the Blue-Ray player or TV's.
I didn't have the guy go over the heat pump/furnace one more time, even though I didn't understand a word he said.
We didn't look on the roof.
Things we have learned on our own so far:
We can't get the Blue Ray player to work properly.
The furnace uses A LOT of propane.
The tank monitor gives the battery voltage, not the percent power they have left (That was a serious DOH! moment, after a day of freaking out about why we couldn't "charge" the batteries more than 13%").
We use a lot less water than I had anticipated.
We definitely need to invest in some good x-chocks.
We also weren't able to drive it home ourselves, because
A: we have't purchased our new truck yet (we will in February)
B: The loaner truck the dealership was supposed to be giving us ended up having some issues.
Bright side: the dealership was super great and had someone deliver the Airstream to us, 5 hours away.
Downside: We didn't end up spending the first night in it on the lot, like we had planned, and we didn't get to practice driving it.
So that's the latest update. Thanks again for all the great advice! Next time I'll try to take more of it
