Even if i go to second inverter which i dont mind, its really the same question regarding which wire connects all the 110. so i can connect it to the second inverter.

I think i can download the electrical panel schematics
The cable that connects your 120 volt duplex receptacles presently goes to a 15 amp circuit breaker in the power center. It should be labeled by where the receptacles are located: bedroom, dinette, living room, bathroom, etc. In a Challenger you probably have 4 different 120 volt circuits not on the inverter. My power center is located in the bed side and the wiring is accessed by a removable panel in the bed platform.

Behind the inverter, there is a junction box for the duplex receptacles off the inverter (TVs, media center, fridge). In the picture attached of my coach, the junction box is just to the right of the inverter in the very back. It is no longer used in my installation as the sub-panel replaced the need for a junction box. The orange 10 awg cable connects the inverter's transfer switch to the power center then connects the inverter's output to the sub panel. The two 120 volt duplex receptacles circuits were moved from the power center's 15 amp circuit breakers to the sub-panel circuit breakers.
