From what I can remember, the Monida units parked fine but the yellow Beaverhead trucks werent supposed to have the station commands at all. Idk though, its been such a long time that I cant remember what was broken on the old version.
Based on everyone's tips, Ive put together the 2 most likely bars that the EMS Excursion could have. The top is the Code3 Defender while the bottom is the classic 2100 bar. Ive also looked into other brands such as 911EP and Star Signal, but none seem to match. A third possible option could be the SoundOff nforce but it seems to be uncommon to the area.
I also doubt an EMS agency in a state such as Montana would use some off brand MIC lightbar.
