Welcome to Forum and your new Airstream.. As a member, you can use "Search" utility in blue bar above, and might search on "quality" or dealer inspections to look for ideas... Thorough walk-throughs and inspections are good, as Airstream has had some issues with cabinets and some wiring, as well as cosmetics around floors and moldings.. Much more leverage to fix before driving home than after... Some dealers do real well to inspect and catch before you do, others can range all the way down to "They're all like that.."
Salespeople often are really focused on selling what is on the lot, and not so focused on what may be on the lot someday, so that is not unusual... Glad it worked out..
