It has one battery which is charged. The front jack as well as the power stabilizers all work. but still not power inside.
any thoughts/help would be appreciated.

There is usually no switch from shore to battery. The battery always powers 12 volt system. Shore power powers converter/charger.
Presumably the light work when on shore power. This means the converter/charger is working.
Without shore power lights don't work, means battery is disconnected or dead.
Tongue jack is wired separately, directly to the battery and it works. So battery is not dead.
There may be a 12 volt power switch near the entry door switch it "OFF" and back "ON" to be sure.
There may be a 12 volt battery disconnect near the battery switch it "OFF" and back "ON".
Some RV's have an inverter/converter/charger. There may be a high capacity fuse in the 12 volt wire from inverter to battery bank. Check it for continuity.
A wire connection may be loose or corroded. Don't forget to check ground (-) wires and connections.

Some of the information is a little dated, but it is still pretty good.
