Hi
I don't know if there is 'off the shelf' units available now. Here's my experience
I fitted braked D11 hubs to my camper (approx 1100kg) about 4 years ago. At the time no one had D11 hubs and Al-CO (brisbane) told me it couldn't be done.
However - I used Late Commodore hubs (stud spacing is the same) and replaced the studs with 14mm (78 / 100 series Landcruiser because I couldn't get LR at the time).
If you use LR alloys, the centre cap will have to machined out by 1 or 2 mm to fit over the outer bearing housing and you will need the 14mm studs for the LR wheel nuts. Steel rims will fit straight on, and the standard 'trailer' studs (actually 9/16) and nuts to suit the 100 LCruiser can be used.
Have not had any problems since it was done.
BUT, the alloys on the Disco WON'T fit the trailer, but the trailer wheels do fit the car. I purchased a set of four alloys from the wreaker so when we do a long trip there is two spares on the trailer and the spare on the back of the car, that gives us three spares that can be used on the car, and two that can go on the trailer, heaps for what we do.
Hope this helps
