Neat arrangement.

Lang,
Totally agree! But, just as an afterthought to what you say about us all being individuals,
sometimes used to think that the services (especially the Army during Nasho days) must have had a diametrically opposed view!
"You "so and so's" lost all your individuality the minute you walked through that gate! Your ASS belongs to the Army Now!"

I recall the first 4x4 Acco I bought ,the suspension was incredible for a truck.......pothole that would have busted your back in a Blitz ,the Inter just sailed over them ........IMHO ,the 4x4 s upgraded a little bit with a perkins and a bit stronger diffs ,should still be the army truck........The British discovered very early that a "quad" with big singles was the best go anywhere truck ...........I dont know why the army didnt upgrade the axles for the 6x6s ,the setup they had was just rubbish ,and very prone to failure...................Incidentally ,all have hydraulic brakes ,and use the same interchangeable components,in the main.....Air over hydraulic.

Bit academic, was only interested if it would add more capacity to the Ford but going by some of the spec's I would not gain much.
One of the sites had a current F350 rated at 8000 GVM with the mods, I have that with currently with the dual rear wheel setup .

Cheers Steve

Precisely...whats the point of all the complication when alls needed is dual wheels on one axle .......entirely for posers ,IMHO.......Incidentally ,there was an old guy in a Ford F450 at the supermarket a week ago ,I kid you not ,it took up four car park spots ..........In the US thse things can take huge trailer loads on just a car rego ........not so here ....trailer weight over 3 ton is commercial rego ,insurance ,licence ,and tow vehicle inspection .

I would have been interested in what sort of increase they would have achieved in the lazy axle version of the 6X2, like that HQ tray.
And it was a reasonable size tray going by the photo. Only ever seen one HQ set up with the dual wheels on the rear, and that for a light tow truck. Had the eight stud rear axle, so possibly a Dana 60 or 70 (maybe fell off a Ford or Dodge??
Likewise there is a 6X4 version of a late model Toyota (again a lazy axle) which was set up as a drilling platform, that's where you would have imagined that out in the desert you would need all the traction you could get.
Obviously someone thinks they are a viable proposition, going by a few mobs still making and exporting them.
Just had a squiz on the net about the Perentie, worth a bit of a read. But does make you wonder why the Oz army unloaded them.

Just because "somebody thinks they are a viable proposition, does not mean they are any good. (I do not know and do not offer any opinion)
A mate of mine, now deceased, ran an engineering works and had a section devoted to making dust removing mats of aluminium strips and wavy rubber strips. He told me they do not work but architects and builders of office buildings think they do, and while there was a demand for them, he would keep making them.

Like this?

It is not the width that is the problem, it is the length.

The F450 I saw ,the old guy (80+) had two old biddys directing him to try and get around the carpark.....the thing couldnt turn in the painted line corners ,then the old guy couldnt back it.....Not the worst ,a while back there was a giant Mercedes mobile home with a 80 yr old driving,(I use term loosely),and he ended up blocking the entrance and couldnt back up ......and it would have had a reverse camera for sure.

Anyone driven a lazy axle truck knows what happens when you take some of the load of a single driving axle ........you get stuck in all sorts of annoying places...........You need a lift on the lazy ,but maybe a 4x4 with front drive would be ok ......certainly not a HQ .
