R850 R sidecar rig or others
 

I'm planning from the USA to Terra Del Fuego and back next year and would like to take a
sidecar rig.
A local dealer has a used R850R and would
like to know if this would make a good platform for a sidecar. if so what models
of sidecar would you recommend?
I would also be interested in which other
BMWs would make a good platform for a rig to
take on a trip like this. I'm not interested
in any K bikes as I really like the looks of
the twins.

Thanks,
Hugh
