I hope this is a joke. I know several people who have bought both RV and Boats new. The idea that either is QA'd 3 times and everything works right from day 1 just doesn't happen.
Honestly i deal with European brands Bavara/Beneteau, Lagoon/Nautitech and each of them have pretty tough QA. Plus there is our own QA on the end prior calling customer onboard and handing over the boat.
I would not sell new yacht without spending at least 5 hrs sailing and testing it prior customer delivery. To make sure all the issues are resolved. In our history we had everything leak in the boat from factory (someone used too long screw when putting up aft protector) that showed only when motoring over 5kt and aft dipped, we had not tied up properly awning, some furniture missing screws, electronic not connected etc. but that's why we as the dealer make sure before even taking customer on board that we make sure its sorted.
Factory always do signup on the configs, e.g. i can follow up any of my ordered boats through whole process from hull infusion to complete and can take customer to have a look at that.
Now i was assuming it is similar with the RV, it being same "luxury" product as yacht and similarly priced (the 35' gas is 120k vs. 38' sailor is 140k) and therefore i also assumed dealers will have same approach, to make sure that customers spending this sort of cash would receive the gods in as good shape as possible.
But i think your last comparison to CAR LOT is probably best explanation i get :-) so i will have to approach it from that point of view :-)
