Cleaning up the mess of battery cables.
My trailer battery's are a mess of wires, the posts were full from the factory then I added wires for the solar, inverter and others. I was thinking about mounting two of these power posts https://www...

The Trimetric shunt on the neg side gets your one fat neg wire to battery while the other end of the shunt has to collect all the incoming negs. So you need another neg bus out from that to help collect all the negs, since the shunt bolt can't take them all stacked up.
Over on the positive side, you might have a battery disconnect switch that has the one fat wire to the battery and all pos wires from everywhere stacked up somehow to the outer end of that switch. The switch probably can't hold them all stacked so you need a positive bus to take some of them.
The electrons don't care how they get there, but you lose some by stacking too many ring lugs. :) A store-bought bus avoids that issue by spreading them out sideways to several terminals instead of stacking them.
