Unladen weight is determined by the manufacturer of the base vehicle. I assume that it would therefore exclude the added weight of the conversion that brings it up to the MIRO.
That's what makes it such a meaningless figure for a motorhome and makes using it to determine speed limits so pointless.
If the pre-conversion chassis weight is used then we're all going to be a long long way under 3050kg. A base chassis probably weighs about 1500kg max.
