The best thing you can do to protect the health of your transfer switch is to make sure all loads (power consumers) in the RV are off when it has to switch. And when pluging into shore power, turn the breaker off on ther power pole before plugging in. Those two steps will eliminate most causes of arcing that destroy the relays in the transfer switch.

But I'v never heard of so many switch failures or such short times between them. You may have something else wrong, but it is hard to say without being able to examine what actually failed on the transfer switch.
