Weight of a fully modded touring GU.

[Cuppa]

Cuppa, yes that is the upgrade in your photo. The problem is, I don't think it increases your GVM but it is less likely to be damaged if you go over it. I have Ironman Contsant 500kg plus leaf packs which have ten leaves, the bottom three being thicker and possible slightly progressive (nothing like the standard progressive). I run the bellows at about 25 psi so as not to over ride the suspension but basically have the weight distributed over three points. The fellow that fitted the suspension said if you pump the bellows up to 90-100 psi, they remove the spring from the equation, effectively like having a heavy duty coil, with all the weight on the one place on the chassis. The way your patrol sits in the photo, I'd bet the suspension has been upgraded as well. Paps.

If you could let me know the details of your airbags I would much appreciate it. Interested too in whether your suspension fully meets your expectations (& what those expectations are). The idea of spreading the load over 3 points seems to make sense. I guess my decision will be multi leaf springs with or without airbags, or parabolics with or without air bags. Whichever way I guess it won't be cheap, but will, I hope, offer reassurance that the vehicle will be fit for remote travel, (even if it doesn't comply to GVM limits).
I'm still shocked that Telstra would have had modifications done from new but not upgraded the GVM at the same time, (OH & S ). It was my assumption when i bought it that all Telstra Patrols had been upgraded, but I can only see the 3400kg Nissan compliance plate under the bonnet.

Ps. I just checked - I also have 10 leaves with the bottom 3 being thicker. No idea of the maker, but possibly the same as yours.
