So, Don, what's the decision - just using Sola and heck with that expensive surge?

Yes, the MOVs used for surge protection are considered sacrificial and can eventually fail if they sustain sufficient surges but in such a case all one needs to do is call Progressive and they will mail out by USPS a new MOV circuit board.

Sacrificial MOVs violate MOV manufacturer datasheets. A sacrificial protector did not do protection. That catastrophic failure is completely unacceptable - considered a human safety threat. Normal failure mode for MOVs is degradation. That means MOVs still operate; but at voltages at least 10% from its original design.

The change of Vb shall be measured after the impulse listed below is applied 10,000 times continuously with the interval of ten seconds at room temperature.IOW MOVs must be removed and connected to complex electronic test equipment. Virtually no one will do that.

Would you care to elaborate on the difference between a protector used in homes versus the PI?

Surges most often addressed in campgrounds are floating ground, high or low voltage, and reversed polarity. To say more requires numeric specs for that model.
