Thingy said:If I am right, they changed the way payload was defined fairly recently. omething about MIRO didnt include a batterry but the payload allowed for one. Try checking the very front of your manual, there may be a list, there is in mine, and this list could vary depending on the age of the caravan. Its a bit odd really, because changing it didnt alter the payload one iota.
This is an article regarding this
Good post Thingy.
The latest Bailey handbook says:
A: MRO (formerly MIRO) stands for Mass in Running Order, this is effectively the weight of the caravan or motorhome as it leaves the factory with no additions. Please note; within the MRO is an allowance for 'essential habitation equipment' ( ie: gas bottle and its contents, toilet flush fluids and mains hook-up cable ) All items listed under ‘product specification’ are included in the MRO.
MTPLM stands for the Maximum Technical Permissible Laden Mass (pre-1998 this was known as MGW maximum gross weight) this is the maximum weight a leisure vehicle can weigh inclusive of the user payload.
User Payload: If you take the MTPLM minus the MRO this will give you your user payload. This is the maximum weight that can be put inside your leisure vehicle when towing it or driving it.
Note the change to MRO. As you said it makes no difference . I expect there are differences between manufacturers but interesting to note Bailey’s take. So contrary to what I and others believed from years ago things have changed in terms of the MRO at point of leaving the factory.
