Don't know if this is related but I have a 322RLDS Freedom Express Liberty Edition and I have now unexpectedly lost all 120v power a couple of times.
Absolutely NO rhyme or reason to it, it just all goes out, once with just the TV on, another with the AC and other stuff running while making dinner. No breakers are tripped, no fuses blown, GFCI didn't trip, just no 120v power anywhere in the trailer. 12v however continues to work.
What I did to resolve mine was turn off all my breakers, unplug from shore power, let it sit for 15 minutes or so, reconnect shore power, and then turn on all the breakers one at a time.
Mine is headed back to the shop/dealership tomorrow to finish the warranty list from last fall and will be adding this as well as a dozen other NEW issues to the repair list.
