Strictly speaking hybrid inverter/chargers don't have an ATS--but rather a type of autoformer. They do have "pass through" capability, if used with the inverter off.
Another possible route is to use double conversion. I often connect4ed just the converter on shore power.
I ran the RV from a 2500 watt inverter (Cobra rated to run motors) $230.00 bucks. The convertor would recharge the batteries when demand was low.
I still prefer a simple plug over an automatic transfer switch. After all--one has to turn all items off with an ATS before activating it. The difference is after unplugging from shore power, I plug into a female outlet in the "mouse hole".
I'm certain what ever method works out for you that you will enjoy it.
Prices on the inverter/chargers have dropped a fair bit. I think there are a couple that are under $1000.00.
