MRO question

[CrewOVtwo]

My MTPLM is 1490 and MRO 1335 (Bailey Unicorn Cadiz).
Rather than make the trip to a weighbridge I'm going to attempt to weigh pretty much everything I put in the caravan.
My search button for the forum isn't working, so can someone tell me if I need to weigh cushions/ microwave/ bed mattress or are those included in the MTPLM?
I have a sneaky feeling we will be well within limits but I'd like to check, with some longer trips coming up.
Once again, thanks in advance 👍

Items that came with the caravan from the makers are in MRO. Things like its step, EHU cable, document pack, external water pump, and one gas cylinder are normal in MRO. Carpets, mattresses are obviously in MRO not MTPLM. Microwave if part of the caravan as supplied by the maker is in MRO. Often your handbook specifies what’s in MRO. Battery is not normally in MRO. But I believe there may be exceptions for large caravan with powered levelling systems.

Thanks. Glad you mentioned battery as that's hidden away in a slot in the floor and I would have forgotten about that - and it is very heavy 😲
Maybe I've not got as much to spare as I thought 🤔

Do NOT rely on the manufacturers quoted MRO
The ONLY way to be certain of your actual, rather than theoretical, weight is to use a weighbridge, be that when its completely empty, or when fully kitted up for your holiday. Anything else will be guesswork.

I think unfortunately your logic is flawed right from assuming the MRO is any plated or quoted figure.
Quite some direct experience, albeit not with Bailey is that the actual MRO can be different to the stated figure, and sadly IME always the wrong way. The makers have tolerances, some even plus as well as minus.
I really feel you ought to accept that in your running state, you get it weighed.

Edit: I see Mr Plodd was there before me and he almost certainly would have knowledge of a lot more actual cases than I have.

 

[CrewOVtwo]

Weighbridge it is then. Thanks again 👍 👍

To refer to an actual MRO is a contradiction in itself. It is either an MRO or an actual weight.

Just to add mud to the waters, I've weighed a couple of 'vans on a weighbridge and their accuracy was plus/minus 20kg. . So that could be a 40kg tolerance. On a medium/small caravan that could be 25% of your payload.. I may be overthinking this and I'd be happy to be corrected.

Okay but IMO that is here being overly pedantic.
I don't think the OP would have misunderstood the point being made, "the weight a van actually weighs in the condition that relates to its MRO, can be different to the value given as its MRO weight, on its plate".

Again IMO, the value to us the user of a quoted MRO is useless. In the final analysis all we need concern ourselves with is keeping its weight within the MTPLM in any state we tow it on the highway.

What the alternative? It can never be an absolute and there’s bound to be some element of variation. But at least it’s better than doing nothing. I used two weighbridges to weigh one caravan. The first weighbridge which was a large public one showed the loaded caravan around 240 kg overweight. The second one in a lumber yard (5tonne) still showed the van to be 240kg heavier than I understood. Shock horror. But it towed beautifully and its tyres were still capable of accepting the overload.

It's possible but so long as I get a piece of paper that says the loaded van is below it's MTPLM I don't care what it's actual mass may or may not be.

At least if you are pulled in for a weight check, you can show that you have been sensible enough to have had it checked.
I had mine weighed and it showed that I was 30 kg overhead stated MRO.
I know have a the Reich weighing scales, good for within 3 %.

Forget the MIRO. Weigh the caravan if you need to know its unladen weight. It's the only sure way of knowing what it is.
