We decided not to go for the fireplace option as well and use that space for a printer, and it has worked out very well. My only suggestion would be to use the rig a few times before buying a ton of stuff that you may find out that you don't need. Also, secure all food items in large bins - on case a jar breaks in transit (only has happened once to us in 10 years RVing), this will reduce the mess.
Congrats!
