    They are all hanging together just fine and all that was required for the GVM upgrade was better rear springs. We also fit rear airbags and decent dampers.

    Definately not a waste of time. Upgrading the entire fleet would cost hundreds of thousands of dollars, GVM upgrades are cheap and effective for us.
    We did that 10 years ago,the Patrols cracked in half and the cruisers cracked hangers and shackes.All GMV upgrades do is move the load to the next weakest part. Pat

    As I said, we haven't had any issues so far, only time will tell.
    The GVM upgrades are issued by an engineer and he didn't have any qualms about allowing them.

    Yeah I have some concerns, but a lot would depend on application, loading and the quality of workmanship. I have seen quality and absolute tripe workmanship.
    Though I personally would not load anymore than 2000kg on them regardless of ratings.

    Pat, I think that is why a lot of people have stopped doing the conversions or at least dont highly publicise it anymore. 5 or 6 years ago there were quite a few doing 6x6 conversions, I only know of one now.
    Personally I would do what a friend has done here and cut down a 100 series and put a full length tray on it with beefed up suspension, but still does not carry any more than a tonne on the back. Departure angle suffers a little but not that bad and I have not seen it hung up yet.

    I had the 2008 model as a 4x4 fire truck and thought it was OK. O par with anything else.

    Might not be too bad. To give you an idea, a guy in the LROCB got his 110 ute lengthened to 130" by a place in Brisbane that normally does similar work on trucks. IRC it cost him $1800 drive in drive out with a mod plate.

    Now that is only about 1/3 of the work of a lazy axle conversion. So bank on at least $6k - if not more.

    Yep, in the pits just down the valley from here the coil sprung rear Patrols would crack the chassis just behind the rear axle (it'd break off) and the leaf sprung rears would crack the chassis at the rear hanger.
    Nissan to their credit beefed up the vehicles in these areas pretty promptly, but I know even a few spray contractors that broke their Patrols in half.
