Craig,

I remember Neil Cocks writing up a GU extension in one of the mags about 4 years ago. Funnily enough he also had a carrymecamper on it. But the following year, he wrote up his new F-truck, so I'd guess he didn't have it for long. I'll see if I can dig up the article at home.

Easiest way to get a longer wheelbase is to buy a 79series .........sorry, bad joke :-))))

Cheers
phil

Don't have cab chassis model but do have patrol 6 wheeler 2004 st wagon with full 8 x6 tray (By 6 wheeler conversions & its the 2nd one for me) & it is great but they do beef up the chassis as they found in the early days some units twisted the chassis my old truck was a 94 model & it was beefed up. They have done a lot of chassis extensions over the years so maybe give bruce a call.
I've noticed over the years talking to a lot of people I've met with extended vehicles that most had steering, spring ,tyre wear & brake ware problems let alone the problems of reduced height when going over humps etc that's why i stayed with the 6 wheeler it carrys the weight well & legal (1.5t GMV 4.5t) & does not get the wishy washy feeling & can tow up to 4.5t legal (if set up right)
The draw backs of a 6 wheeler 60/40 weight (not straight lazy axle they are a problem)
1) un loaded in rough ground will loose traction in the back quickly
2) rear tyres will wear edges of but will last about twice as long as the rest
3) a bit of extra fuel because of the extra weight (not noticeable unladen)
that's about all of the bad problems, but you do get a lot more benefits & every time we go bush our vehicle is not overloaded even though we are carrying more gear than most so we get a lot less ware & problems
good luck
regards Vince

Vince,

Did you consider making it into a 6x6?. That is the ONLY way I could ever conceive of doing the '6 wheel conversion' I'm afraid. I need that positive traction ALL the time......not just "most of the time".

Cheers

Craig D,

I scanned an article from 4X4 last year where Ron Moon went through the same process but extended his wagon about 600mm. I have created a PDF file of this. Send me a member message with your email details and I will pass it on.
