Jim, someone recently purchase PI, but they still have the liftime warranty, if the unit is not mis-used.
"Our Lifetime Warranty covers only Progressive Industries’ workmanship, internal electronics and parts & materials contained within the unit housing. Any and all damage to the outside of the unit is not covered. External damage is typically associated with a poor connection between your RV or our EMS/SSP units and a power cord. The Lifetime Warranty does not cover labor or shipping charges."
I can vouch that they stand behind the units, got a new one at absolutely no cost.
