Transfer switch suggestions please.

I have a Honda 3k (with remote start) and an inverter installed in my 2014 Bighorn 3685RL and would like to add a 3 position transfer switch. (process below very confusing for my wife and adult children)
I ran a 30 amp plug to the 'genie' locker (wired into a separate circuit breaker at control panel) When dry camping I turn off main breaker and turn on genie/inverter breaker.
Currently I and have to unplug from genie, plug into inverter (and turn converter circuit broker off) when switching from genie to inverter..or visa versa.
Seems an automatic TS would be a waste of good $$ as I need to start genie remotely and/or turn inverter on/off anyway so I'm thinking of a 3 way, 3 pole rotary TS to switch between shore power/genie/inverter (wired so that converter is off while in inverter mode to avoid The Loop)
Anyone have a suggestion on above switch? Or any other suggestions to simplify the process?

Hi dickhe,

There are things in your description that are unfamiliar to me. Maybe draw a nice sketch, snap a pic on your phone and attach it here.

I used 2 TRC Surge Guard transfer switches side by side
the first one has shore power as main input and Gen then from there it goes into the 2nd switch which has the Invertor on the other side then on to the breaker box.
It all works automatically..... no need to switch anything.

2 of those doesn't seem like a bad price for autonomous operation. $85 ea.

If you are stuck on a single switch here's one 3 position 30 amp rotary switch.

Curious as to why 2 switches vs a single 3 way switch? Any chance of "collision" if both switches on at the same time? (I do have an EMS for shore power)

Let me try again. I ran a 30 amp line to bow locker (houses both genie and inverter -G/I) from dedicated circuit breaker in panel. When using genie or inverter, I turn main off and G/I breaker on; and visa versa when on 50 amp shore power (main on, G/I breaker off)
When on genie or SP I leave converter on. When using inverter, I switch converter off to avoid creating a loop.
Seems a properly wired 3 way switch would do all the above with 'the flick of the switch".
It seems 2 pole 30 amp 3 position switches appear plentiful. I think I need a 3 pole 3 position to tie into 50 amp 4 wire SP system, (using only 2 poles for 30 amp G/I part of the system).
Hope this clarifies a bit.
