Bob,
Have you considered converting your power system to 50 amps? I'm seriously considering just taking out the WFCO converter/30amp breaker panel and installing a Progressive 50amp breaker panel/60amp converter. The specs look good, there's a 50 amp main breaker, 12 aux breakers and 18 DC fuse circuits rated up to 20 amps. Of course the usual reverse battery protection fuses, 3 phase "smart charging" etc....
Total cost for the panel is $217 from one source, may find it cheaper somewhere else, I haven't really looked yet.
My thoughts on the conversion is simply to remove/replace the Marinco 30 amp input fitting with a 50 amp fitting, larger romex inside to carry the two legs of A/C, connect the existing trailer wiring as it is on one side of the new breaker panel, add my circuits on the other side and simply reconnect all the DC to the new panel just like it came off the old panel.
The only "extra expense" would be the 50 amp power cord, and since I've already got the 30 amp cord, I plan to use it (lighter weight) unless I do wind up needing a second air conditioner.
I was looking at installing a 20 amp aux breaker panel to run a heater, etc, but saw that a new complete panel isn't that much more than the parts to add the smaller extras....
I know it's do'able, just need to find a warm place and some time to check things out, develop a parts list and get it all ordered. Here's the URL for the panel.
