Old thread I know but I have been concerned with weights on my camper. I have a revenue weight 2,320kg and the handbook gives 1,900Kg as vehicle Mass (Curb weight so assume 420kg payload). Obviously being a conversion I do not know the new curb weight but it would be close to the original even with pop top as you loose the roof metal and sunroof glass and mechanism and the 5 rear seats must be close to the conversion as it is all light materials. Interestingly when shifting through my digital manual I found the attached specification sheet, it gives the following for weights (I used the ANH20 CVT as this was closest to my model)
Curb weight front 1045-1055Kg
Rear 850-870Kg
Total 1895-1925Kg
GVW Front 1,140Kg
Rear 1,385Kg
2,525Kg
I guess the answer is to have the vehicle weighed to find out axel weights in normal operating condition and use the GVW axel weights but keep combined below revenue weight.
