How long can my dual cab tray be ? Engineers Qu. Vic.

[BrettInUte]

OK - So Im doing a Nissan patrol GU dual cab conversion.

Cab is cut. Full length tray is sitting there.

Cant get onto my engineer currently to clarify.

Can someone confirm exactly what the maximum length of the tray is ?

Or more precisely - how much overhang can I have after the end of the chassis ?

I have been told 300mm from the back edge of the chassis
AND
300mm back from the towball.


Grinder will be out this arvo if someone can clarify.

PS - Im in Victoria.

dont know if is the same but got told that trucks were allowed 60% of total wheelbase behind rear axle may be the same for car.

[BrettInUte]

just had it confirmed.

rear overhang is allowed to be up to 60% of your wheelbase.

overhang includes towbars or tray.

Although i can't imagine you having such a big overhang, but its 3.7 mtr or 60% of the wheelbase whichever is the lesser.

Nissan Patrol GU, Manufacturer's Specifications

* station wagon, 5+2 seats, 4 doors, driver air-bag (passenger air-bag and ABS brakes on TI)
* loa: 4885mm, width: 1930mm, height: 1855mm
* wheelbase: 2970mm, track: 1605mm/1625mm, grnd clearance: 200mm


So - 2970 x .6 = 1782

So I can have basically a 1.7m tray (tray starts basically directly above rear axle line)


measuring that now - I have almost 900mm unsupported past the end of the chassis.


hmm. Im going to go back to about 1.6m and add an extra support down to the rear of the chassis rails - just in case !

Just double check but I think the 60% of your wheel base rule only applies to trucks over 4.5t gvm, utes is only 1200mm I think, but correct me if I"m wrong. Went into it awhile back with the rta at Darra with my truck cause I needed to carry more than 60%. With trucks you can go more but it's a lot of stuffing around.

Have you tried your engineer since you posted this originally? Thats where I'd start.
