Camco Power Defender 30 Amp Surge Protector
Protects RV electrical system from surges and open grounds during hookups.
This plug-and-play surge protector monitors voltage, open ground, and reverse polarity, automatically cutting power if issues arise. At under $100, it's a steal for RV basics, far better than no-name $30 units that fail quickly.
Compared to premium Progressive models ($250+), it lacks auto-resetting but offers 1650J protection sufficient for most 30A RVs. Users rave about its LED diagnostics and durability (4.5+ stars on Amazon). Perfect value for budget campers protecting $20k+ rigs.
