Pros
- Costs about a third of a 50 amp EMS
- Warning lights flag a bad pedestal before you plug the coach in
- Weather shield and Lexan housing for living outdoors on the pedestal
Cons
- 1,650 joules is low for a 50 amp coach
- No voltage cutoff, so low campground voltage still reaches the appliances
