Rob, thank you for looking up the vehicle, I will e-mail you on the DIN from work.
There were actually two Suburbans at Div HQ - Callsigns 99 and 99A. From 1982 until at least 1999 the Div HQ went through three different vehicle models for these callsigns. In the early 1980s Jeep Cherokees were used, then there was a switch to Suburbans and two models of these were used.
I have photographs of all of them, just a matter of getting the thousands of photos scanned, here is 99A in Kingston in 1996.
