I think there are many dealers and manufacturers deliberately ignoring the issue. I fear that there are also more than a few owners who whilst not actually deliberately overloading are aware their vans are marginal and choose not to to check and carry on regardless.I don’t agree. I don’t think folks deliberately overload their vans either.
As I said earlier it would suit me well if the weight limit was increased. However if manufacturers just add more space and lots of tempting goodies we will have the same problem but at a higher weight.
My suggestion would be that an increase should be accompanied by a new minimum actual payload for vehicles based on the vehicle weight at handover. Meaning that dealers are not allowed to hand a motorhome over if there is less than say 500kg real payload based on the vehicle weight that day.
