The last week we were in Yellowstone, the power pole we were plugged into shorted out and fried our Progressive Industry (PI) surge protector. There was 85 volts on one leg and 165 on the other. Fortunately, it didn't hurt the bus.
I called the owner of PI and told him what happened. He sent me another unit even though mine was well out of warranty, and the problem was certainly no fault of PI. Another example of excellent customer service.
