Defender Cab Chassis queries

[austastar]

Hi, what is the maximum tray length on a single cab ute?
I gather a tray is allowed to extend past the rear axel by 60% of the wheel base, so a 110 will be shorter than a 130.

Has anyone replaced the coil springs with airbags?

cheers

my 95 110 tray is 2275mm(2340ext)It's a TRIPLE M alloy tray & the spare (7.50r16) fits under rear partially ontop of fuel tank.The tray needs to be this length to get spare up and under back.Tray deck is made of sections about 6" wide that clip & bolt together.It has a 450mm overhang but is usually not a problem-though last week I was about 400kg overwieght taking some calves to town and maintaining a straight line on the road proved interesting:( wont be doing that again! I think a combination of weight+overhang+full fuel tank & rear mounted spare made front to light-am considering bonnet mount for spare to balance load better as I'm quite often loaded to max & will travel with lighter fuel load next time

Here's a tip - when I had my single cab trayback I was forever wishing my tray didn;t extend as far - made for a few interesting moments when tray gfot hung up on things the rest of the vehicle handled without drama.

Hope this helps. We (dad and i) made the tray for his 130. We pretty much made it the same size as anyother dual cab ute think thats a 6x6 foot give or take, given this we knew the travel on the fender is pretty much double what anything else is, so without a picture i'll hope to explain well enough. We put the spare on the fuel tank pretty much lifted the tray on to it and messured and gave a little bit of room, fits the spare under and is about chest hight looks way to high but it doesn't hit and we can put a 1000lt shuttle full of water on the very back. or maybe i should just get some photo's of it..............:D
I guess if you build it around a single cab ute tray of any type you can't go to wrong.

I've got this one sorted by scaling a brochure illustration from the known wheel base, and calculating a 60% overhang.

A standard 2800 tray falls 400mm inside the maximum over hang.

Howdy, sounds like you are all over the regs regarding over hang, max rear overhang is 60% of the wheel base or 3.5m which ever is less. Wheel base is measured from the centre of front axle to centre of rear axle, then the allowable overhang is measered from the centre of the rear axle outwards.

This is the same for carying objects on the roof ie ladders, timber etc. You are allowed 1.2m in front of the car measured from the face of the headlight and then the rear is the 60% rule.

I haven't been involved in this sort or capper for a few years now so things might have changed, best check the ADR's to clarify.

Good Luck.
