I hope also that this trailer build up can remain in Members Build ups because the end result of the trailer build will be a custom tray built for the Triton.
Here is what I'm thinking and a couple of pics too kick off with.
The trailer will be a combined camper/trail bike carrier. The camper being my tub, canopy, and rooftop tent as it is set up on my triton. The bikes will be located on the chassis/drawbar. (KTM 525, KTM SX65, TTR 110 and TTR 50). They will be stacked from large to small. If the need comes to travel solo without a trailer the tub etc can be easily bolted back onto the triton.
I'll start with 3/4 of an ML D/cab chassis. I've decided to go with using a chassis for ease of bolting on my tub and dual rear wheel carrier off my triton, etc.
I'll modify the chassis in front of the transmission crossmember bringing the two chassis rails together welding a plate under the rails and bolting a hitch through the plate between the rails.
I'll get the rear springs reset 3inches higher and with a 1600kg load rating. This way the trailer should ride at the same height as the triton, and will pass inspection.
I've ordered an axle with electric brakes, will have a built in 80lt water tank across the front of the tub, and a fuel tank under the trailer (position to be determined depending on weight distribution) to refuel the bikes.
This is a start, I have 101 other ideas rolling around in my head, we'll see where they lead.
let alone something that'll be dragged behind the car at 110 kph! 
Maybe she know's me better than I think!!
