Wow those weights aren't great!

I hear the y62 series 5 has had an update to the suspension and the tow ball down force table has gone?
Does anyone have the spec on the series 5 weights? the Max is:
Gross front axle capacity (kg) 1650
Gross rear axle capacity (kg) 2030
according to the Nissan website, but what is the kerb weight on the front?

I think I'll get airbags in the rear for towing, I expect to have an unladen weight around town, and a touring (towing) weight which airbags should help with. (I have a forward fold camper Trackstar Omaroo 3 that is 250kg+ on the ball) Airbag-man bags, you manually inflate are reasonably cheap.
Redarc Tow Pro elite 3 is what I plan to use, It's the same as what is in my current vehicle.
Still not sure about a front bar yet.
Decided on a tradie style rack. Wind noise sounds like a pain, is the rhino really that loud? hmm

Sounds like the front springs need to be upgraded with the bullbar if it's going to sag a lot. Still no word on Nissan's OEM bullbar.
