I’ve been a Ham off and on since the 1970s - in and out of the hobby/service during that time (seen by the FCC as a service due to the capabilities of ham radio, such as the current situation in Louisiana).
In the van I run a 2 meter rig that I mostly use for APRS tracking, but it’s capable of Winlink email, voice and digital repeaters, and of course simplex comms (FT-2980). Just installed the necessary hardware to run a portable HF radio for long distance communications using SSB, CW, and digital modes. The HF portable rigs I have are Ten Tec Scout and Yeasu FT-857D.
All runs on my battery/solar system. Doesn’t use any more power than the TV.
Let us know what you use.
