Id like to understand this system and its capabilities before purchasing one of these trucks .

the short version...

theres a 24v system and a 12v sytem built in to run and test light weight power units like radios for repair.

theres a 240V system that in some vehicles is run from an inverter and in others requires external power like a generator (the inverter one can also use a generator)

the long version is in the EMEI.

I spent many a year in a G’mer

The 12v terminals are only hooked up to one of the Aux. batteries, this used to kill one battery way faster than the other.

We ended up purchasing a 24-12 converter, this worked way better as it drew from both batteries.

Good thing Engels run off 12 and 24, although with no low voltage cut out we used to destroy batteries.

What are you plans, they are a heavy pig empty.

Have a close look at the hinges on the full wings, I suspect some would have issues creeping in.

From memory there used to be a battery charger passenger front....we removed ours.

Can anyone identify what items are what in the pictures ?

Im interested in one for an extended bush expedition type trip for start of my retirement . Spend a couple of years in the tropics qld nt and wa . Top end exploring .

I’d personally look for a cargo, if the G’mer is cheap enough ditch the pod.

pic below is pretty much what you see and read. I wouldn’t run off the 12v terminals, I’d buy a 24-12 tranny. I’m trying to remember the trick we used to do for the 240v Power. Have you got a pic over the 240v power, it’s under the flat rear drivers side of pod.



The black box must be an upgrade, I recall that where the 240v battery charger, again just low voltage outlets. Vice used to store below. The blue ish box might the control the lights/fluros


the yellow box above the bench holds the fuses and circuit breakers, a volt gauge and a couple of selector switch to choose battery or 240 power.


The steel drop down bench is Friggen heavy, we used to leave the vice which made it even heavier.

I wonder if the 240v heater is still at floor level up the front of the pod. They generally got ditched as it took up valuable storage space for either water or goffa’s we’d sell to the grunts.

Back to the lower in, I think there might have been two 240v circuits, 15amp socket for power in, we would than run a small lead from a power point in the roof driver side rear around to the outside box to power up the lighting circuit.

Hmm...we rarely used the 240v side as I’d refuse to take the generator. Again valuable storage space taken or it meant towing. Neither were a high priority as having copious amount of water for showering or cartons of goffas was way more important.

Ive done some online research tonight and found the pod version is 400-450kg heavier than the cargo . Almost 4000kg opposed to 3500 or slightly more .
I see your point in heavy truck . I like the solid fibreglass though for tree scrapes down the sides rather than cutting canvas sides . Also lockable is good and long life in the weather could save buying new canvas from time to time .
These are the only reasons I like the fibreglass .
How poor would the performance be affected as opposed to a cargo version ? Im guessing biggest drawbacks are slow , fuel consumption and getting bogged .

they're heavy and they soak up load, they bog in and chew rubber as well as suspension bushes.


one of the ones I craned out of the global explorer back in the day may have had the crane computer getting upset on a nearly 10T radius,
