I don't want to make it seem that I don't understand your frustrations because I and many many here completely understand.
It seems that most of these issues could have been addressed by your dealer during their inspection upon arrival at their lot.
Obviously your not a new RV owner so it hurts that much more trading in a unit that the bugs have been worked out only to feel like you have been taken. If your dealer is a stand up outfit they will make these things right and you will have many years of trouble free camping in your future.
Hang in there and keep us posted.
