We have the SouthWire Surge Guard 34951. It's the only one with load side protection, meaning that it will detect faults in the RV as well as at the pedestal. It also comes with lifetime protection insurance so that Southwire will pay for damages to your RV in something gets past it.
We also got the optional bluetooth remote monitor so we can monitor the loads on L1 and L2 from inside the RV. With it, I could finally convince Joan that she can run nearly everything she wants to at once and not blow a breaker
Southwire and Progressive share 90% of the market according to an article at TechnoRV.com

We actually own two of them, with one as a spare so we are never unprotected.
