For anybody who is in the C&MC I've started a thread on the Club Together, Discussions, on Weights and Payloads.
A pet gripe of mine is the heavily over loaded wwb, owners filing every storage hole just because it is there without any thought for real payload.
A month or so back the magazine had a huge twin axle, 5 berth I think, with a payload of little more than 100kg by the time the couple of movers required would have been fitted.
It might be interesting to see the replies.
