This is an Australian military No. 5 1/2 ton trailer.
Over here in Australia you see people making all types of modifications to these - adding RTTs, installing slide-out kitchens and such. Sadly mine is pretty standard.
I was after a 4WD trailer which I could simply use to extend the cargo carry carrying capacity of the BJ40 during an outback trip later this year. No roof top tents or slide-out kitchen for me. In the trailer I want to be able to carry a minimum of six jerrycans (4 x 20l diesel cans and 2 x 22l water cans), spare wheel, a space case, and a big tent. The interior of the trailer has tie-downs which are left over from its military service where each No. 5 trailer was fitted with mounting points for a water bladder.
The trailer is a tub-type like the American M416 with no tailgate. If you lash two empty jerrycans to the drawbar of this trailer you can paddle it in the water like a dinghy. Like most military trailers it is fitted with a lunette ring hitch system.
When I bought it, it was painted camouflage, and since the trailer was built in 1963, I decided to bring it back to its Vietnam-war era look. To do that I needed to give the trailer a complete respray in basic olive drab, then make up a canopy bow and finally source a canvas canopy. This work took a couple of weeks and now it's a good, honest trailer which is perfect for remote outback use.
The only other modification I am making to the trailer is to have an axle made up which will accept the same 6-stud Toyota 16 inch split rims as the tow vehicle. At the moment the trailer is fitted with 5-stud Land Rover wheels. They work fine, but they aren't split rims, which means I can't fix the tyre myself out bush and the Land Rover wheels are quite expensive compared to the dirt-cheap Toyota split rims. I've gotten a quote for the new axle and it's not too bad actually - around A$400 from hub to hub. I'll get this axle made up in May or June.
The tow vehicle has a tow bar with a Hayman Reese style towbar fitted. So far I have tried two different styles of pintle hook on the vehicle. The first type is a solid hayman reese compatible hitch. It works fine, but sits a little too low. The second is a plate to which a separate pintle hook can be bolted. This one gets the trailer's drawbar to the right height, but due to the plate, I can't unlatch the stock spare wheel carrier on the 40 and the tailgate wouldn't open either. Plan C is to remove the Hayman Reese towbar and bolt a pintle hook directly to the factory mount using the four holes.
Here are some pics of the trailer.
