30 amp for duel AC

Device looks very similar to Progressive Dynamics cheater box. It specifically says no GFCI and receptacles must be on separate circuits.
Cheater box

It is nothing like a cheater box. This unit is hardwired into the RV. Two different animals.
What I find interesting is you guys are making the same mistake I almost made. I was too quick to dismiss the switch as a cheater box or some other gadget that would not work on GFCI etc.
I saw it as some Rube Goldberg gimmick that would trip breakers or work sometimes and not others. Just like you guys are thinking I was wrong.
At some point I cleared my mind and actually listened!
Once I paid attention to what the maker of the device was actually saying vs. thinking I knew what he was going to say. I realized that if his device really worked as advertised it would be a real game changer.
As it turned out I was the guinea pig a bought the device.
the device works as advertised. Essentially it allows you to run your 2nd AC off of the 20 amp circuit at the pedestal. The device works on GFI circuits and non GFI circuits.
I used the device at MB state park this summer in 100 degree heat and it worked like a champ on a GFI circuit.
Simply plug in 30 amp cord as normal and then plug 2nd dedicated 20 amp cord into pedestal flip switch to pedestal mode and your set.
All circuits are UL approved and breaker protected.
This is not your grandfather's cheater box!
Last year I booked very few 30 amps sites. I avoided them like the plague because I need both AC's blowing to keep unit cool in the mid Atlantic heat and humidity. This meant I avoided lots of state parks and older places with only 30 amp service. This upcoming year will be different. I no longer have to fear 30 amp sites. I plan to put a few of my old destinations back on the itinerary now that I have the 30 amp solution!
All I can say to you doubting Thomas's is that it works! Yes even on GFI circuits
