sxitoes said:Hello I was wondering if anyone could help I have a Elddis Whirlwind dates I think to about 1985. It has a single front window and solid door with no glass. Does anyone know the kirb weight, and the max load weight so I cant have another plate made?
Many thanks in advance.
As far as I am aware there is no legislation governing the MTPLM of the body however if there is it would be interesting to read up on. Actually i don't think there is any legislation regarding the MTPLM.ProfJohnL said:I'm not sure when the legislation came in, but currently, the coach builder determines the max vehicle weight (MTPLM) regardless of the chassis manufacturers capacity rating.

I think legislation regarding chassis was introduced in about Oct 2012 where there had to be a mandatory plate fitted to the trailer chassis and it had to be registered with a VIn number.

You are free to choose whether to use or ignore the information I have supplied at your peril. The VIN number will be registered to the coachbody manufacture not the chassis manufacturer , and thus their MTPLM figure is the one used to determine if a given trailer is overloaded.
Maybe I am misunderstanding your reference to a coach builder? I am sure that the body work of a caravan does not have a VIN number, but the chassis on which it is built probably has a VIN number. However going back to the OP, I wonder if they have found a sticker or plate with the details on it. BTW the link you supplied is from a trailer organisation and not a gov website so hardly official as these type of sites tend to make up things as they go along. 😉ProfJohnL said:Hello Buckman,
I am not getting mixed up. CRIS had not even been mentioned.
see
https://ntta.co.uk/safe-legal-towing/trailer-maximum-weights/ This plate would be fitted by the coachbuilder as the chassis manufactures limits will be overridden by the final manufacture to handle the chassis.
It is the equivalent to an HGV plated weight limit, which may have bee derated if the maximum weight the vehicles will handle in use is less than its mechanical capability. This is done to improve teh tax efficiency and is often the case where a commercial manufactures products have a low density.
It is the plated value the authorities will use to assess if teh vehicle is being used above its authorised mass.
ProfJohnL said:I used the term coach builder to differentiate it from the chassis manufacture and it relates to the company that builds the body of the caravan/ motorhome, or any superstructure not supplied by the chassis manufacture.
It is a common enough reference used throughout the motor vehicle and trailer industry.
I agree the site I pointed to is not a government site, but it is far from the noddy type organisation you casually accuse it of being. It is a well respected organisation that lobby's on behalf of the trailer industry, and as such it is highly knowledgeable on the legalities of towing.
I would most definitely believe the accuracy of its web site over causal commentators on a forum.
Just out of interest the Camping & Caravanning Club
https://www.campingandcaravanningclub.co.uk/helpandadvice/technicalhelp/datasheets/matching-car-caravan/
state
"The standard MTPLM figure for caravans given by manufacturers is calculated according to the British and European standard BS EN 1645. It's technically known as the MTPLM (Lower Limit) and in some cases this can be increased to the MTPLM (Upper Limit). This Upper Limit is based on the physical limits of the caravan itself, such as its chassis and axle limits. If you have a suitable towcar and your driving licence allows it (Data Sheet 40 - driving licences has detailed information about the limitations of a licence), you can ask your caravan dealer to - replate - the unit to the higher MTPLM with the resulting increase being the amount of luggage and other extras you can carry. It's important to do this because if you are challenged by the police or insurance company and questioned about the legality of your outfit, it's the figures given on the plates and accompanying documentation that will be used to validate your statements."
The NCC state
"Maximum Technically Permissible Laden Mass (MTPLM)
(Maximum Authorised Mass)
As stated by the caravan manufacturer on the caravan weight plate (usually mounted close to the entrance door) – the absolute maximum weight that the caravan must not exceed to be legal on the road. It includes the allowances for the user payload – all fluids (water etc) and personal belongings that you may wish to carry (clothes, food etc)."
I presume you consider both these astute organisations make up answers from thin air also.

'Does anyone know the kirb [sic]weight, and the max load weight so I cant have another plate made?'
The newbie didn't ask for an in depth discourse on the legalities of vin numbers or chassis plates.
