Meaning of these numbers on my weight sticker

MIRO is the weight of the van as it leaves the factory.

MTPLM is the maximum permissable weight of the van.

Not sure about the highest weight.

It would help if you could post a photo of the weight sticker or at least give us exactly the full wording on the sticker.

The very fact that the MIRO is shown suggests that it's not the statutory weight plate, because MIRO has no place on that. If the caravan was built after 2014 there should be another (statutory) plate somewhere else on the caravan (usually in the front locker) and it would be interesting to know what that says.

Yeah I tried to attach a photo, but this forum software hasn't shown it. Honestly this is the worst forum website I've ever used, it's so sloooow.

Anyway, I'll have a look for the other plate. The one I'm referring to is on the outside, next to the door.

Ah this is interesting. According to this site https://www.caravanguard.co.uk/news/2021-adria-altea-tyne-caravan-25025/ 

the weight is upgradable to 1800kg. So I'm thinking that this sticker indicates the increased weight capacity. 

Put it this way, I'm saving myself £150 and I'm showing the police that sticker, if needed.

The label next to the door is not the official weight plate. It's only there for marketing purposes.

You'll find that the official (statutory) weight plate will only show one MTPLM of 1800kg. The label by the door just says that it's marketed as 1650kg.

Was it like this⤵️

That's the NCC label, not the official weight plate. It doesn't comply with the requirements of Construction and Use regulations, but only serves to inform for marketing purposes. Whether it accepted by the police or other authorities is purely discretionary.

I'm really curious, and I should know this. But where is the official weight plate on an Adria caravan?

It's something the van documentation should tell you, but sadly doesn't.

Yup, something like that. Very similar info. However nowhere does it specifically say MTPLM, which I would have expected it to do so.

Which is why I'm doubting it's the proper one. Think I'll spend some time hunting around the van, although you would expect it to be obvious.
