Are you saying that NONE of these devices we are discussing are any more effective than a home strip surge suppressor because we don't have an effective ground within 10'?
Stop jumping to subjective conclusions. Deal with individual facts one at a time. If making conclusions from subjective beliefs and emotions, then every reply will make you feel like a child.
Stated were numbers for that one protector. Understand the significance of those numbers before making any conclusion. Why assume numbers for one anomaly define all protectors for all anomalies? Why jump to that unjustified conclusion? Therein lies your first problem. You want to be indignant rather than first learn what stuff does for each anomaly - with numbers.
Defined is why that one protector function is ineffective. Nobody said anything about earthing a rig. By remembering what Ben Franklin demonstrated over 250 years ago, or by remembering how electricity works, then earthing a rig would make damage easier.
Did I ignore other benefits such as detecting polarity, missing neutral, etc? Obviously not. Why did you ignore those first two paragraphs? Each completely different anomaly must be discussed separately.
Thumbs up or down are for consumers who want to be told how to think (also called brainwashing). Informed consumers learn how to separate scams from science. That means every reply and question should include or be based in perspective. That means numbers. Your every speculation is devoid of spec numbers. You want to assume all anomalies are same.
What do 2600 joules in that Surge Guard do? Nothing useful. Do those joules protect from other anomalies? No.
Does a Surge Guard protect from reverse polarity? Protect what? Reverse polarity does not harm appliances. Polarity is a human safety function. So what is being protected?
Does it protect from phase variation, frequency variation, excessive harmonics, or EMC/EMI? Apparently not. Is that protection required? Your answer should include numbers. Since each potential threat must be defined BEFORE recommending any solution. And each discussed separately.
Does it protect from an open safety ground? Apparently not even though that is a too common anomaly in campgrounds. It really should detect that anomaly.
Does it protect from brownouts? Say so with numbers. Is that protection necessary? If making conclusions from subjective reasoning, then tell us why. Remember to list what in an RV does and does not need for protection.
Of course 2600 joules says nothing about these other anomalies. What numbers exist so that one can make a conclusion?
Long before demanding a solution or being indignant, first define each threat. Which anomalies require effective protection? Tell us which anomalies are of concern in a campground - with numbers. Only then can a solution be discussed.
