Had a similar problem on our last trip in our 2015 Axis 24.1. No power to anything except those items plugged in to an outlet (we were on shore power at the time. Slide, Awning Fridge, AC all down. The coffee pot and microwave worked (both are plugged in) Although the 100 amp wasn't tripped, found 2 blown 40 amp fuses in the house fuse box. They are between the 110 and 12v sides. Replaced and all back to normal. My conclusion was the items not working either ran on converted 12v or were controlled by 12v and were all builtin to the electrical system.
