Autoformer
What would be the proper sequence of using an Autoformer and a surge protector from coach to post?

rfsod48,
If you have a 30 amp service, surge protection is less important.
If you have a 50 amp service, an open neutral can fry everything in your RV. Progressive Dynamics top of the line would be my choice.
Far more items are damaged by brown outs than by surges.
For the best protection, be "off the grid" and go large solar. Probably you have to give up air conditioning.
For second best, use an autoformer followed by a top of the line surge unit. Again Progressive because of their life time warranty.
You should check the power source before you plug in, not afterwards, even if you do have protection.
Here is what would do:
1. check voltage under load (both legs if 50 amp)
2. check polarity
If that passes then
3. plug in surge device
If the surge device gives a "green light"
4. unplug surge and plug in the autoformer
5. plug surge device into the autoformer.
