12-volt power for macerator pump
Our newly purchased macerator pump requires 20-amp, 12-volt power. Have you found a simple way to supply that power to the pump? I'd like something that would plug into our 120-volt house power.

In my opinion using 12V from the trailer batteries is the best option. I ran 10 gauge wire from my batteries to a connector in a nearby compartment as wa8yxm suggested and it was easy to connect/disconnect when using the pump.
If you decide to go the power supply route you'll need more than a 20 Amp supply. When you turn on the motor there is a starting surge that will likely trip out a 20 Amp supply. I suggest at least 30 Amps, something like a Meanwell ERPF-400-12 (around $50) would probably work OK.
