Hey Alt,
You really should just bite that bullet and fix it right the first time. It's an 18yo coach and someone has connected something to the chassis battery that should not be there. So, pop the hood and look for what got added first. If you don't find it, attach two wires with alligator clips to a small (like interior light size) light bulb.
Put that in series with the main engine (aka chassis) battery and start pulling fuses and disconnecting things. Neither the keep-alive power for the ECU or the radio should light a small light bulb, but if something does, find out what it is.
When you have that found and removed, the find a Trik-L-Start or similar to keep the chassis battery at full charge.
