Most Thor MHs use a standard double-DIN radio form factor; so any double-DIN form factor radio will work.
The replacement will NOT be plug and play - you will need to wire the harness/connector that comes with the new radio to the chassis wiring.
Where the switch box is depends on what Year/Make/Model MH you have. Most are under the dash.
The switch box supplies power to the cameras and takes the 3 camera feeds and supplies the video to the radio via an RCA style plug. Rear view camera is always fed to the radio by default. The turn signal tells the switch box to change the video feed to the appropriate side camera.
The switch box also triggers the radio to switch to the camera input whenever the transmission is in REVERSE or the turn signal is activated.
Your new radio only needs a backup camera input and trigger which 99% of all new radios have.
