SPD Required on RV Pedestal

[B677]

Running a new conduit and 1/0 feed to metered earth buried pedestal GE1LM532ES

Inspector dropped requirement for GFCI but wants SPD. This pedestal likely does not allow double tapping the lugs for a type 1 SPD. Looks like it only has one double pole breaker slot open.

Looking for ideas to install a SPD.

Thoughts:

• Remove single pole 20A and replace with double pole 20A
  • One leg of SPD to breaker
  • Other leg pigtailed Breaker to Receptacle hot and other leg of SPD
  • Never done this but technically both poles of the breaker are in use; is it code?
• Polaris with 3 ports
  • not sure there will be wire to use these on in the customer side of the RV panel

Anyone have any good ideas?

'Wants' or 'can cite code for SPD' ?

RVs are full of electronics. Most owners have their own SPDs. I am pretty sure the SPD requirement is for dwelling units
