I think its connected to both: It has two power leads:
- A switched power lead, and
- An always on lead
I think Thor connects the switched lead to the house battery, and the always on lead to the chassis battery.
I put a knife switch disconnect on my chassis battery (and another disconnect on my house battery). In addition, when I replaced the radio I connected both power leads to my house battery (the new radio has a GPS and thus there really was no need for it to remained powered up simply to keep the time).
