Not unlike any RV I have ever owned you will always find little things that the factory workers just don't care about.
First thing I always do when I purchase a new rv is start tearing it apart to check on things. Here are a couple:
All the sinks leaked at the drains, some plummers putty and back in business
One of the Vent lines from the furnace to outlet was just laying loose and not connected to the furnace, so the underside of my Fridge would have stayed nice and warm.
Cable wiring is probably the most common
Perhaps a section in the forum where people can post the common errors they find with rv construction. As we all know there are a ton of them and being aware is always good. The most dangerous are those who trust in the manufacturer to assemble their unit correctly, they are the ones who lose out because if they are not aware of the things that not right they can have some serious issues after the warranty runs out and usually that revolves around water in or water out
