Question Installing an inverter

I intend to add a residential fridge and go off the grid in the up coming year.

Additionally adding solar panels.

My question is what components are needed to distributed the power through out the coach.

I assume I need something to cut out the inverter if I plug in.

I need a wiring diagram of an install (excluding the solar I know that part)

My assumption is I need to run romex from the inverter to the main box but something needs to cut that power when plugged into shore power.

I just bought this coach and was surprised it didn't have one.

There are several different ways to add inverter power to an RV. Simplest is dedicated outlets where you want/need 120VAC. Much more costly way, actually there are two ways, replace the standard converter with an inverter charger or add a separate inverter and an automatic transfer switch. Your choice based on how much money you want to spend. Remember adding solar panels is only the start of the project. You will probably also need to add more battery storage to support the whole program.

I have 2 6V house batteries now and plan on adding 4 more.

I already have a 55watt converter installed.

I don't want to segregate different outlets, just do all

I guess I need a Inline Transfer Relay switching between shorepower and inverter AC source.

Most of the inverter/converters installed as original equipment in MHs have built-in transfer switches (in addition to the MH's main transfer switch) that switch the batter bank in or out of the circuit depending on whether you have shore power or generator power available. In our MH almost all of our outlets and light fixtures (120V lighting) go through the inverter and are fed from a 30A breaker in the main circuit breaker panel. The inverter itself has a subpanel following it with two 20A breakers in it.

Yeah...transfer switches are almost always in the big inverter chargers that you'll need...easiest way to understand it is with an install here is one!

Note the transfer function under section #3.

Differing ways to do what you want. Will vary due to what you already have and how best to integrate the new items. Attached is write-up with block wiring diagram of my solar and inverter(s) installation.
