I'm sure that the wiring harness has the plugs for things like the map lights and bathroom vent switches so how much could it cost to keep these items. Probably not much. If they said it would cost a few bucks more to keep them I surely would have paid the money but you don't know that they have been deleted until you use the coach for a while and realize that they are missing. Another thing is that the brochure that was online when I bought my '14 was for the '12 coach so you don't know what's been deleted until you, as I said, use the coach. Not really something that you look for during the PDI. Also, they changed the water filter and you can't buy the replacement cartridge from anyone else but FR at 30 bucks a pop. On your '08 you can get replacement cartridges at Home Depot or Lowes for much less.
Oh well. Not much you can do unless you really check each and every item installed in the new coach and the old coach.
