A 600-amp busbar with eight posts, which is enough for a full build - inverter, alternator charger, solar controller, fridge circuit, lighting, winch feed and still room left.

The cover matters more than it looks. An exposed busbar in a truck bed is a dropped spanner away from a very bad day. This one comes with an insulated cover that stays on.
