Hi All,
Been lurking around here for a long time, and finally have finished my Caravelle / Multivan rail install into a 2022 T6.1 LWB 4Motion.
I've put together the attached layout with the part numbers I used, as my way of giving back to this forum!
I live in Australia, and my engineer/certifier wanted the custom angles and flat bar installed in the rear of the van, in addition to all the other OEM brackets. Obviously check with your local authorities in case you need to do something similar.
Note, if you use the OEM rivets, do yourself a favour and buy a compressed air rivet gun. Being stainless, they are extremely hard to set with a hand tool!
Anyway, hope this helps someone, cheers!
