Some of/or most of these things should have been caught by the dealer before you picked it up. The factory normally doesn't fire up the fridge, that is what they dealer is supposed to do for a PDI. It is called a Pre Delivery Inspection for a reason. They should go through the whole unit and correcting any things the factory missed. Now don't think for a minute that I don't think Lance should have missed the screws and latches and all of these items but that is also what the dealer is for. Did they give you a walk through and make sure everything worked to your satisfaction before you signed on the line buying this camper?
I do feel your pain when you give your hard earned money to them and then they could care less if they deliver you a good product or not. I think Lance is falling down on a lot of their quality checks that should be performed by the factory.
