I have been a "HAM" radio guy since the early 50s... Always have some sort of setup everywhere I go...  Camping off the power grid is no different.
My setup is pretty well described here by viewing my floor plan drawing of the OFF-ROAD POPUP trailer.    I am also as much setup with the same equipment in my Truck mounted under the rear seat with remote heads on the truck console. All of my HAM RADIO equipment is setup for 12VDC operations...  Tent bed ends not shown here...

I use my current three 85AH battery bank which will soon be upgraded to two 150AH batteries in two separate battery banks one on the trailer tongue and the second one in the bed of my truck. The plan is to run everything form the battery banks during the day/night and re-charge the batteries when needed using the 2KW Honda Generator which will re-charge the batteries to a 90% charge state in a short three hour generator run time.
I like to use good marine quality BLUE SEA MARINE products for all my electrical needs...
This is my planned electrical wiring for the truck mounted extra 300AH of batteries.

Most of my camping off the power operations is using the all band screwdriver TARHEEL antenna along with the 2m/440 roof top mounts.   I do have a fold-up small three inch tri-tower that is mounted to the trailer and will get me up to around 15-feet where I mount my all band off-center dipole antenna.   This works out great for me.
I am engaged with the HAM RADIO RACES/SKYWARN/NAVY MARS emergency radio operations and I would like to extend my setup on the VA/WVA state line up on the George Washington Natl Forest (Flagpole Knob area) and act as relay for VA operations during exercises... I have full computer setup as well in my OFF-ROAD popup. Another must these days for HAM RADIO.  Great camping time too as well...
My emergency radio service is really being hampered now with all the local and state police/rescue squad radio operations going to their digital radio setups.  This is making all of scanner operations pretty much obsolete now.   Things are always changing...
