1970s CF Radios

Thanks to Darrell Z, I am now the proud owner of a manual on the VRC12 series of radios. It is very informative.

My questions to our radio gurus, re:RT-524A, I am wondering what the usual configuration was;
RT-524A (VRC-46), or
RT-524A w/R-442 (VRC-47), or
RT-524A w/R-442 x 2 (VRC-48)
RT-524A x 2 (VRC-49)

I am thinking as my M38A1 CDN3 was an armoured recce veh that I want to portray a correct comms jeep of the era. I have dual mounts for antennae and am leaning more towards a dual radio configuration. I would like to do the most common representation.
I want to have an operational setup (yes I know about licenses etc)

Not being well versed in radio jargon, here is how I understand it.
The 524 was a receiver/transmitter. The 442 was strictly a receiver.
I assume that in the field 442 sets would be tuned to other frequences from other mobile units (manpack PRC25 or 77 sets) and then to be re-broadcast on the 524 set, perhaps to a command center? If not, what was the purpose of fitting 442 sets alongside the 524?
What was the reasoning behind dual 524 sets? (VRC-49)
