The only radio in my C is in the dash. I was thinking about installing a 2-way which would control the power to the radio either from the chassis battery or house battery when I'm camping. Has anyon...

I added a switch and power from the coach batteries. In my Chevy there are 2 wires with power. One is ignition key powered. The other one is always on for memory. The key operated wire is the one you want connect to the new switch. The other side of DPDT ON OFF ON will to coach batteries. Current radio in dash has a remote to make it easy to use when on coach power.
You only need a SPDT switch here. The center off position would also be optional, but it would be wise to make sure that the switch is a break before make switch (so that the two batteries are not connected together through the switch as it's being flipped). Having a center off position is one easy way to ensure that the switch definitely is break before make.
Assuming you have a typical battery isolator setup that charges the house battery when the engine is running, there's really no need IMHO to switch the power source to the chassis battery, so I might do away with the switch entirely. (Actually, as a matter of fact, my RV came from the factory with the dash radio wired to the house battery only...this is one area where there is no standardization among the various manufacturers.)
