2017 Thor Freedom Elite 29FE

The radio should be run off of the Factory fuse panel (under left side dash-kick panel area). The 20 amp fuse is Number 39, see diagram here http://www.autogenius.info/ford-e-series-e-450-2015-fuse-box-diagram/
Where it gets tricky is if there is a House or Chassis radio switch, then you should be able to test power at that switch and chase it from there. Obviously if the fuse is blown, the next thing to find out is Why. Good Luck

Then, if the odds are good that the Dashboard Radio is powered through the House Battery "Salesman Switch", is the House Battery charged?

House Circuit Fuses are usually part of the "Load Center." On newer RV's that LC is probably a single unit containing

1. 120 VAC Breakers
2. 12 VDC Fuses
3. 120 VAC ==>> Converter/Charger
(4. maybe... 12 VDC ==>> Inverter)

Do you know where that Load Center is?

RV builders are notorious for hokey wiring. It could be connected outside the LC. It could originate at LC and still a fuse elsewhere.

Since this Radio includes a Backup Monitor Screen, when it WAS working, is some condition needed to make it work (like engine running, in gear, in reverse, the like) that isn't met right now. Or even a relay involved?

Most Class C's at least, have Dash Radio powered by either Chassis OR Coach.
Winnebago had a switch to let you choose.
Our first one was Chassis powered, so the Key had to be in ACC. Well, ACC also caused the Step to operate every time we opened the Coach Door. Wired it to Coach instead. Then the display became a parasitic load so I had to add a switch.
This Jayco has an ordinary aftermarket AM/FM/CD radio. If Engine is running, it'll play with the Coach Battery OFF. If Engine is OFF it won't play till Coach is ON. I don't know how it does it but it's sweet.

Do you have the battery switch turned off by your stairs? The radio will not work if the coach battery is turned off. Or at least that is the case in our Thor Chateau 26B.

Thanks, Dave! The battery switch is 'on'.

It's a dash radio that includes, among other items, the rear view camera display. Probably a coach fuse panel. Ford chassis. Now that you have that information, can you help me with my question?
