I use a similar splitter about once a year. Personally, I don't see it being much more different than plugging in an extension cord into the spare 15/20 amp outlet to power stuff on your patio table like lights, stereo, griddle or small compressor for air toys.
Recently, I added two additional outlets in my coach, one in the main cabin and one in the bathroom, that are powered by a separate cord that plugs into the power pole. The separate outlets let me run an electric heater or hair dryer without it running through my inverter circuits, plus it helps from overloading my circuits when only 30 amp is available.
I agree with Diplomat, it's good to get all the information and opinions and decide whether it is useful or not.
