Radio Only Works With Ground Power

I'm new to Airstreaming and just bought a 1988 345. My am/fm car radio seems to be hooked up so that it only works when I'm plugged up to the outside ground outlets. Won't work running down the road. How should it be wired up. I thought it would trigger off of the ignition switch just like every other vehicle I've ever owned. If it should, then does that also mean that it shouldn't work at all without the key on, like while camping.

Any thoughts?

Find a wire that has power at all times, you may have selected a feed (hot wire) that is de-energized when the ignition switch is turned on, or if you power the radio when the ignition switch is in accessory mode.

Isn't this the same set of symptoms as your lights? (

I know they wire the radio into the coach batteries instead of the ignition so if the kill switch for the coach batteries is in the off position the radio will not have power while driving and it explains why it works when plugged in, then it's running off the coach's 12 volt convertor. They do it that way so you can play the stereo while camping and not have to have the ignition turned on. That could be the issue with yours...
