Welcome to the forums! Sounds like you are on the right track! My recommendation is to find a floor plan you like and dealer you can work with, those are the two most important things.
The next is to do a thorough walk through of the unit prior to signing on the dotted line, if things are not close to right don't be afraid to walk away. If the unit has a few glitches (I have yet to see one that doesn't), have them fix them prior to the purchase contract being signed, then go for it.
