120 AC panel Board (Help)

[Rust]

I have a new 2011 flying cloud and want to wire an inverter to run some small appliances on the road during stops,and I will be leaving for a month vacation next weekend and wanted this done.
My question is how do you access the panel board since it is located behind a solid panel in my trailer or are they all in this location.
They have a cut out but not right in front of the panel and access is limited.
I want to no if I have to cut another opening under the seat to be able to reach in.
Service repair must not be easy for the technician.
Thanks George

No familiar with the 2011 but if you want to run an inverter you need it located as close to the battery as possiable. Connect it to the battery with large enough wire for the inverter size and run the output of the inverter to where you want to plug something in.

In other words a short run for the 12VDC and the longer run for the AC.
