Did you have a pre-delivery inspection walk-through ? It sounds like most of these items should've have been picked up at that time, like the screen door, toilet, vents, etc... They should've gotten everything working for you at the dealership: A/C, heat, and walked through the unit with your to ensure things were tightened down, doors worked correctly, slides functioned and sealed properly, awning worked correctly, etc...

However, some of the items you listed may not have been able to be identified during the walk-through, which is why a short camping "trip" in your driveway, or somewhere nearby is advisable before a major trip - to be able to catch things like this with a new RV.

It sounds like a trip back to the dealer is in hand... have them go through it with a fine tooth comb, and then you do the same when you have that all-important detailed walk through with them again before you drive off with it this time.
