Using manual transfer switch to distribute power

[TimeOutside]

The application is providing AC to a camper. The goal is to provide AC input to charge a solar 'generator' when the camper is connected to shore power. Then, when the camper is disconnected from shore power the transfer switch is moved to Position #2 for the solar generator to provide AC power to the camper. To accomplish this goal I tap into the camper's existing distribution panel bus bars.

1. When the manual transfer switch is in position #1
   a. Shore power is routed to a Jackery solar generator. The Jackery is limited to a 15 amp AC input, which is the reason for the breaker.
   b. AC output from the Jackery is disconnected.
   Note: AC output from the Jackery is off by default. A button on the unit must be pressed to turn on AC output.
2. When the manual transfer switch is in position #2
   a. AC input to the Jackery is disconnected.
   b. Power is routed to the camper's distribution panel from the Jackery's AC output.
   Note: The circuit breaker is needed here, but I provided it as an additional cutoff.
3. When the manual transfer switch is in position #0
   a. The Jackery is isolated from the circuit.
4. Note: There are positions still available on the transfer switch. I intend to use a couple in Position #2 for some DC distribution that is completely isolated from the AC distribution.

Is this wiring correct? If not, what corrections do I need to make?

Thank you,
