According to my info, the fireplace is standard on the 272RL. I think it's a change order to replace it with a cabinet, although with the outside kitchen the cabinet wouldn't be very deep. If it helps any I can give you a link to the "invoice" of the actual model that was up there. It's listed with the MSRP though and not the discounted price. We also are adding a second a/c and upgrade to 50 amp. Not sure if you got a price for that when you were up there? but our quote for it is an additional $750.
