Adding 12v circuits

Hoping someone might be able to help. 1992 Blue Bird TC2000. I'm not trying to do anything fancy, just want to add 4 12v circuits for a few accessories. The electrical panel is so complicated. I'm seeing a bar that has a bunch of wires attached, I'm guessing that is the positive terminal but there aren't any extra spaces on it. Should I just double le up on some of those + terminals? Can I just ground out to the body or do I need to bring the wires back to a ground in the electrical panel? Also any recommendation on wire gauges when I get around to installing. Thanks for any help!

get a test light and have a friend do the key on/ key off, while you check those posts for power. you can probably locate a hot terminal like that to use.

the negative terminal will have a lot of wires attached to the same screw in the fuse box. crimp an eyelet onto your wire and add yours. or like you said, you can find a ground closer whatever you add.

Blue Sea makes some nice DC equipment that you can add if you want to put more circuits and fuses off of the hot you pick.
