I use a poop battery, which is a spare deep cycle battery that sits around and is trickle charged, then brought out for use. This way, the macerator pump is independent of the charger, and 20-40 amps needed to start and run the pump are easily available.
It worked very well to use jumpers to tap into the trailer battery, my jumpers are long enough, and the extensions I crimped onto the pump leads were easy to clamp onto. I placed a piece of plywood under all the connections, everything is portable as well. I was actually amazed at how well it worked. I am not mechanical/electrical at all, and this did work!! :C For a short term fix this worked nicely. Now my rig is winterized and I'm not heating it anymore. This is my first winter, hopefully all will be well!
