It's HIGHLY unlikely that any sink trap will 'slosh' out while traveling, you're not doing tumbles or leap frogs, just driving... the p - trap is not going to slosh out just due to driving.... but, it IS possible that, while draining your Gray/Black tanks before leaving, the 'siphoning' effect can come into play, pulling out the water that is in your p - traps, including the shower and kitchen sink.
We've had smells before, usually WHILE driving and a window is open, or the roof vent is open... it stinks, too!, but is from the GRAY tank, which smells a lot worse than you might think! We solved the issue by making sure to run about a cup or two of water into each drain, including the shower, after dumping, and before traveling, ESPECIALLY if it is temperate weather and a window or vent will be open.

As for the lav sink draining into the black tank - it makes no difference which tank it drains into, as far as that goes. If you think that 'just because' it drains into the black tank that you have a special case, you'll be wrong. Many, many RVs are designed this way - it's no accident. The general reason is that is just much simpler to have the lav, which is close to the toilet, use the same tank. Running the lav drain plumbing across the coach, or down the line, just to have it combine with the other gray tank items is not always necessary. Ours does this, and I've never considered it any type of 'defect'... the engineers are not always right, but most of the time they know what they are doing, and the reasons why... though, it's true, it's not always immediately obvious to us users.

as for your other warranty or build concerns, that's what your warranty is for, and that's what manufacturers like Thor EXPECT you to use it for. They build RVs... they ship them to dealers... dealers sell them to you... you use them and find all the 'faults'... Thor repairs them. Relating buying a car, which is more of an 'everyday' event for the public, and produced thousands per day, is TOTALLY different than RVs, especially motorized RVs like motorhomes. There is way too many variables in each unit, versus a car, and they are produced one-at-a-time, by people, with no robot interference! Sad that some folks have many more warranty issues than others, and sometimes this could be the difference between dealers and their own in-house inspections of new units, but the dealer is also there to resolve these issues, even after-the-fact. We feel your pain.
