Best advice I can give is to make sure you conduct a thorough PDI.
There is a sticky in the Tech Talk section that has the whole process spelled out. Dress accordingly and bring some tools and a dolly. Be prepared to spend 6 hours or more, if you have no help. And don't let the dealer push you around. Its your RV. Get everything documented on an RO before taking delivery and be prepared to leave the unit an extra day so all the things you find that can be addressed immediately can be taken care of.
