Along with the recall, the Internet is rife with problems associated with that IOTA transfer switch Bill. I see no problem with you removing it altogether if you do not have a generator OR an inverter. Be sure to use an approved, listed electrical box to make the connection between the shore cord and the load side of the coach’s system. It can be mounted right where the transfer switch is located now. Tape the wire nuts securely also. I would also label the generator-ready wires inside the proposed generator compartment to alert future owners of that coach that a modification was made. Leave the conductors in place but label both ends of the generator circuit just in case someone eventually installs a generator.
A transfer switch (either manual or automatic), is only required when more than one source of 120-volts AC is available to power the coach circuits. Some transfer switches control all three available RV sources; shore power, generator and inverter. In an RV equipped with only a shore cord connection, the conductors simply end up at the main panelboard breaker box anyway. There is a junction box somewhere in the circuitry of those coaches that transitions from the stranded shore cord conductors to solid romex wires inside the RV. So without a generator (even though it's prewired for one) and no inverter, you can safely bypass and remove that failed IOTA transfer switch.
