I have one that I purchased several years ago for $99.99. It does work as advertised and it WILL NOT work with a GFI plug. I don't know how it can be built for 30 bucks considering what the plugs sell for.
You need to remember, your not going to get the total of 100 amps that your present 50 amp RV is looking for, but you will get a total of 50 amps instead of only 30 amps without the unit. So your only ahead by 15 or 20 amps. But that makes it doable with energy management.

hershey is right on that it doesn't work with a GFI plug and the rest of his post. This ebay device is known as a cheater cord (and other names) and there are many related posts on these boards.
They work and can be useful. HOWEVER they can cause problems depending upon the CG configuration and other information. The discussions on these boards involve in/out of phase circuits and neutral over loading. It's very technical but the posts are available.
also if the CG has the 2 plugs wired on the same pase you can burn up their wireing cause your breaker may be on your post and the post in the panel may not be fused.

I am not absolutly positive, but the box sates "UL Listed" and I have a difficult time finding that true. The UL labs would find this dangerous, because it has two input plugs and one output.
If they hooked it up to a stove, turned the stove burner on, and then plugged in one of the plugs, they would quickly find that the other plug sparks if it is near a metal surface, causing the product to fail it's safety "Giggle Test".
While I would build and use one if I had a 50 amp RV, I could not use it at the following places, and that means about 95% of the RV parks I have been to recently.
Any RV resort with a 20 amp GFI, it will not work, and NEC code requires a GFI in most "Wet" locations, so if the power post is outdoors . . .
At Morro Bay, the feed to each site is #10 wire protected by a 30 amp circuit breaker, that is always locked up, only the Ranger and other staff can re-set the circuit breakers, and the 20 amp and 30 amp receptcal are both fed from the same circuit breaker, 1 for each site. This type of set-up it will not work in.
At another campground, I had two power receptacles for the double site. In this case, if management allowed, and there was not a second camper in the double site, I could use the two 30 amp receptacles with a device like you described, but management considers this stealing power, and would kick me out of the park if they find and confenscate such a device. It is in the rules of some parks. They consider it a danger to their wiring system, right or wrong, it is their rules.
So where I would have a place to use one? I don't know.
There are simple ways to load share. Without getting one of these devices or upsetting the management. You can use an extension cord to power your electric water heater and refrigerator - if they have external power cords, just plug them into a #12 gauge extension cord, and plug that into the GFI protected campground power plug.
If you have a 30 amp and 20 amp circuit breaker and the feed is more than 30 amps to your site, then you could use whatever the water heater and refrigerator use together along with 29.5 amps to power other things in the RV.
I find that I use my voltage booster more often than the 30+30 to feed a 50 amp RV would be used.

Money can't buy happiness but somehow it's more comfortable to cry in a Porsche or Country Coach!
well Fred has pretty much said it all but I wonder just how well an airconditioner will run/start up on 15 amps, especially if there is a bunch of other stuff on that circuit.

In fairness his listing does say:
"NOT FOR USE IN PARKS WITH GFI RECEPTACLES."
but the whole idea of this providing a 50A service is just plain wrong. Perhaps it provides HALF of a 50A service. (50A @ 110V but certainly not 2x50A @ 110V).
