As I mentioned earlier, I had clipped the converter coil wires on the original converter because it was putting out 20+ volts. I was just running everything with the "converter" switched to battery and using a 1.5 amp trickle charger to keep the battery charged whenever we had shore power. With the new 5 amp NOCO charger I could have just kept with that plan.
However, I decided that was not very elegant, so I purchased a 15 amp power supply from Amazon.
First, I connected it to 110v and checked the DC output. 12.08v seemed fine, much better than 20.1v from the old converter coil.
Next I patched it into the old converter circuit where the coil had been and turned on all the
lights and turned the Maxxfan on high. I let those run about three hours and monitored the power supply for excessive heat. The result of that test seemed acceptable to me, with just a little heat detected.
Lastly, I decided to mount the power supply in the rear bunk, on the bulkhead separating that space from the Duo-Therm heater.
I know, a lot of screwing around to maintain the appearance of the the original PD converter.
