Having inverter issues. (Long post)
When I bought this coach it had an inverter that was not also a transfer switch (separate charger and inverter) so there was one transfer switch that controlled the switching between shore power and g...

Looks like a single pole 30 amp transfer switch in the inverter. This transfer switch should not be used with a 50 amp RV main feed to the breaker panel. Get a 50 amp transfer switch and wire the output of the inverter to L1, L2, Neutral and Ground. The 50 amp transfer switch will isolate L1, L2 and Neutral and prevent the feedback issue you are having. Secondly the 50 amp switch is the proper rating to pass through utility power when available. Nothing should connect to the 120 volt inverter input.
As an alternative you could wire the inverter after the main panel to feed a subpanel. Here you would pop in a 30 amp single pole breaker to the main panel to feed the inverter and internal transfer switch. Inverter output would go to a small subpanel with 15 and 20 amp breakers as needed. Then you move branch circuits you want powered by the inverter from the main panel to the sub panel. This will also prevent feedback in all conditions.
