Yes APX series is slick. In our older JK I used to have a dual deck single head. That gave the wife all 4 bands with only one O7 control head. My work truck has 2 dual deck APX setups. So basically I can be on any 4 bands at once on any radio.
I have a XPR with HHCH sitting in the shop to install but DMR is basically defunct in my area for ham and commercial in UHF so never put it in.
Right now my jeeps all have a mix match of stuff -
09 JK - APX8500 w/HHCH, Kenwood TMD700 (APRS), Midland 275, Uniden CMX CB
18 JK Rubicon - APX8500 w/HHCH, Midland 275 (Jeep Model) and Yaseu FTM400 (APRS)
20 JT Gladiator - APX8500 w/HHCH, Midland 275, Uniden CMX, FTM400 (APRS)
2023 Drag Pak Challenger - 8500 w/HHCH (hidden in center console)
