Well I had an 1100 built for a friend it had EZ before the serial number registered in 1999 but it was made in 98 that had the grey stained wood on it, no question in my mind it was the original wood. I guess its possible that someone changed out on the OP's grill but I don't think so that would had to have been some enthusiast. Not sure and probably totally wrong but I don't believe I have ever seen a 3000 with the Durawood thinking since that grill is an upgrade they still gave you the wood but who knows this grill is flat out beautiful.
