If both starting and house batteries are under the hood, hopefully they will be labeled, usually the house battery is on passenger side. If not, disconnecting one will result in engine not starting and no power to head lights, the other will be the house battery.
In that era, with batteries under the hood, there was only space for one 12 volt "deep cycle" RV battery. Nowadays, there are often two Trojan T-105 6 volt golf cart batteries connected in series for 12 volts and longer duration power for interior lights, furnace blower, and water pump. The two 6-volt batteries are in a compartment under the step in our 2004 Tioga. You should check voltage at your house battery with your rig connected to shore power. With good battery, should read 13.6 volts if converter/charger is working and around 14 volts when truck engine is running. House battery will last up to three days with frugal use of interior lights, etc. The furnace blower may completely discharge the house battery in one night when not connected to shore/camp power. You can convert to two 6-volt golf cart batteries but requires some serious effort.
