Payload

CrazyCaravanner

I have a Bailey Orion. It has a MIRO unladen weight of 1100kg, with an MTPLM fully laden weight of 1247kg , giving me a payload of 147kg. Are the factory fitted items such as battery, cooker, fridge and microwave included in the MIRO, or do I have to deduct any of the weight of them from the MTPLM please? Information I have read seems to be conflicting, so now I'm a bit confused.
