Wired before the transfer switch also gives a way to have 110 power if the surge protector fails... Can start the genny.
I went with portable over hard wired in part so I could choose to not use it if the unit had an issue - without tearing apart the rig.

Any with a delay will save the rig... that includes Progressive and Surge Guard... but I bet you will be replacing the surge protector...
Granted a difficult/unlikely thing to do - the only likely scenario is someone incorrectly wired an RV 110 30A outlet with 220... Anything else wouldn't physically plug in..
