All this is pretty normal in the RV industry, really.
Since you are probably going to need them, first thing I do on a new RV is take all the drawers out, open every access panel I can find, and collect all the screws, wire nuts, wrenches, plumbing, and other spare parts they have left for me there. Then vacuum all of the construction detritus. Take a good look under, inside, etc. so WHEN stuff breaks or goes wrong you know where to start looking.
Not knocking Lance particularly, they are just trying to compete in an industry where the standard of excellence is astonishingly low.
