Twin battery set up with winch fridge etc . I run this set up myself, for donkeys years,
1. Joint the two batts pos to pos with a h/d abttery switch eg hella, with the big red key. This will enable you to connect both batteries when winching, and allow max current from alt to both batteries.
2. Connect anderson to second battery again via h/d battery switch , so that you can turn off inside cab as with the sort of people about these days you dont really want a live available outside vehicle JMHO
Why have you got anderson connectors , is it a demountable winch?
3. connect distribution point to second battery (i.e your eightway fuse box. ) Connect all accesories that you dont only use when moblie eg fridge, rear floodlighting ice. inverter etc.
4. I use 12v socket for fridge , keep cable as large as possible, and as short as possible , to prevent voltage drop, and maintain voltage as high as poss.
5 . I dont use split charge set up as I just switch on second battery to main battery connection as part of start up procedure . KISS
