Indeed it does the same things, its just that it is cheap Camco ****. When it blows, what are you going to do......... trash it, thats what.
The Progressive industries unit, in particular, is US made, and has a lifetime warranty. If the surge supression blows, you can open it up and they will send you a new surge protection board to install, or you can send the whole unit and they will fix it for free.
I have a hardwired unit (some people have a variety of reasons why they don't like hardwired, but I'll avoid that discussion for now). It has a remote readout that constantly reports voltage, freqs, amps, and reports error codes. The remote inside is nice, I can see the draw of the A/C, water heater, microwave, etc, and what needs to be turned off before I turn on something else.
The cord units also have a digital readout of this info.
Camco doesn't show you voltage, just says it will protect you from over/under voltage by disconnecting. Camco gives you very little info about their unit. Does not state that it disconnects or will not connect upon detection of reverse polarity, or hot ground, just that it "detects" it, it might, I do not know. No mention of a time delay to protect your A/C. If you are gone, and the A/C is running, and power drops or goes hi/lo, or whatever, the Progressive unit disconnects, and STAYS DISCONNECTED for 136 seconds, to give your A/C pressures time to settle out, before restarting the power. If your A/C has an internal time delay (my '07 does not) then you can opt to have it only delay 15 seconds, then power on if all is well.
Everything is better built about the Progressive, the power plugs, the cover over the female receptacle, the digital readout, I'll bet it has a much better quality relay in it.
Some things you cannot protect for, nearby lightning strikes pretty much cannot be stopped by anything portable, possible nothing will stop them, but your worst worry is brown outs, and mis wired/loose wiring in campground pedestals and wiring.
Progressive 30 amp in the new style is $256 on Amazon, and the older one is still listed for $233. Not a lot of functional difference between the two. The Technology Research Surge Guard 30 amp is $242, and it functionally similar to the Progressive but not as good a warranty.
You get what you pay for...............
