Surge Protector and Extension Cord

I have a Progressive Industries EMS (superior in functions to Surge Protector -- the PI unit shuts down if low voltage, a much more common problem than surges in RV parks), as well as surges.

Saying it doesn't make it so - there are several TRC Surge Guard models, including portable versions, that offer low / high voltage disconnection ... to suggest otherwise is simply not factual. :S

No need for hostility, sir.

I've merely pointed out that what you claim to be true is in fact not the case at all ... and anyone considering the purchase of one of these surge protection devices ought to be aware of the differences.

As enamored you may be with your PI portable unit the reality is it suffers the same drawback that units similar to it suffer - it's not field repairable and must be returned to Progressive for any repairs. I've just solved this issue by ordering a hard wire version that is ... and that is fact. ;)

Product competition and choices are a benefit to all of us. You can buy what you like. I'll buy what I like. And OP can buy what he likes. Re the Progressive Industries units, another thing I really like about them is they carry a Lifetime Warranty. And one does not need a receipt and does not need to be the original purchaser. I have had no problems at all with mine, and it has performed flawlessly even in violent storms. But it's a nice feature, if ever needed, to be able to send it in to the manufacturer, for free repairs.

Clearly you don't fully understand how these products work, as anyone who considers any surge protection device to be a one time purchase that will never need repairs may eventually be sorely disappointed. The fact is that surge protection in these types of devices designed for RV use, regardless of brand, is based on MOVs (Metal Oxide Varistors) which by their nature degrade each time they sustain a hit, which eventually can result in total failure. Your own EMS has most likely deteriorated, you just don't realize it, but the bottom line remains the same regardless of whether it's a PI or TRC or any other brand - over time, given enough hits (most of which you're not even aware of) those MOVs can fail and would have to be replaced. In most cases, regardless of brand, that means returning the unit to the manufacturer for repair, one exception being PI hard wire versions that are field repairable by the owner, which as I said earlier is one of the reasons I've invested in one myself.

As for the terms of the Progressive Industries Warranty you're incorrect that it is transferrable to any subsequent owner - it's not, applying only to the original owner. Blindly promoting one brand over another simply because yours "has performed flawlessly even in violent storms" is a disservice to others considering an investment in one of these devices as doing so doesn't address the true facts of the matter.
