Both the driver side front headlights and rear tail lights are dimmer than the passenger side.

Also, the radio does not work when I have the headlights on. What should I look for? I added a ground to the rear harness to the body on the passenger rear side.

I am running a generator.

I have the dedicated ground on the radio from the main dash harness. There is a ground on the dash cluster.

You're still losing a ground somewhere. Those are classic symptoms. Could be corroded connection or bulb socket issue, but definitely losing a ground in the circuit.
