Rally, maybe nick up to the local rubbish tip and ask them to weigh it (empty).
Add back the towball/hitch weight to get the real tare weight.
I keep meaning to do this with my rebuilt trailer to find out how much I lied to VicRoads when I registered it .... :iconwink: :ebiggrin:
The weight I quoted to them was a
very rough estimate ... :rotfl:
IIRC, I said it weighed about 350 kgs. I would have to check the paperwork. Mind you, it's pretty solid too. Bloody idiots asked me how much it weighed fully loaded! I said "Because it's an un-braked trailer, it cannot weigh more than 750 kgs GVM, as then it would be illegal." They weren't very impressed, but didn't know how to argue against this :lol:
. They tried to tell me that the GVM was the total spring rating!! Bureaucratic fools!
[Another EDIT]
I told them 250 kgs ...

Even though the MDC unit is as solid as heck, I would very be surprised if it weighs 700 kgs even fully optioned (with the water tank empty, and nothing in its panniers - IOW, as delivered). Only way to tell for sure is to weigh the flaming things, I reckon!
[EDIT]
I have looked at the GIC web site and the weight they quote here:
https://giccampertrailers.com.au/camper-trailer-packages/extreme-off-road-camper-trailer/
appears to be for the trailer alone. IOW, maybe it doesn't count the substantial weight of the TTT, and possibly not the lid and its in-fill panels?
Anyway, weighing it will tell you the truth. The latter appears to be a fairly scarce commodity these days
