Forgive me, Prof. I do understand it. However it seems that Bailey have therefore designed a caravan that is either a) impossible to load with overloading the front front axle or b) easy to load without overloading the front axle but making the van wildly nose-light and therefore highly dangerous on the road.
I'm sorry but this shows you have not understood the detail of the weights and limits and their interactions related to caravans.
The limits the Bailey/Al-Ko caravans have given are perfectly reasonable and rational, It all depends on how you distribute your load within the caravan as to which proportions of the load are supported by the wheels or the hitch.
As I pointed out previously trying to work with loads that are so close to the limits is massively complicated, and you should be applauded for trying. But it's become so complicated because you're trying to eek out the odd kg here and there and you are working right at the very top of the margin and there is so little wriggle room.
it is highly unusual for any one to take it so seriously. I'm not suggesting that is wrong, But I do agree that some caravanners may well be running illegally without realising it, and apparently getting away with it.
But that is not a reason to allow complacency to rule becasue it is no secret that with modern technology it is possible to take quite accurate axle load measurements on fast moving traffic. There are trials of such systems in the USA and I believe some UK port authorities are testing them for commercial and safety reasons for loading ferries.
Even if these systems only highlight a possible issue it could be enough just cause for the police to pull any vehicle over for a more detailed VOSA investigation.
