Dealer I have been talking to got me a list of some options that don't show up on the build sheet but you can get from Redwood. Thought some might be interested if they are getting ready to order.
Electriccook top, delete carpet in living room, heat pads for tanks, and gas line with connect located under baggage compartment door side.
Here is a link to a 2014 38GK they have with the cook top and carpet delete options. http://www.carolinacoach.com/RVInven...-RW38GK14.aspx
