So, the blown fuse turned out to be an I-D-10-T issue. When I crawled up
under the hood of the new (to us) motorhome to change the oil (they do not
make this an easy task...) I noticed a box way over on the left side
labeled "Battery Control Center (Fuses Inside)". And buried therein was
fuse # F17 'Cargo Lights'. Which indeed was blown. Maybe Thor (the
motorhome manufacturer) was trying to tell me to check there - but I
clearly described the place I had checked was the Ford "Power Distribution
Box".
