I know a tad about power draw and amperage, I did monitor my voltage closely by external means and my 96 Vogue's built in monitoring meters. I mention the age of the motorhome only to indicate that it has no power shedding features. I ran both airs all day long in greater than 90 degree direct sunlight( little to no shade),voltage stayed at a constant 116-117 volts. I only mention this because generally, I would not even think of trying this but a employee that I know at this park had mentioned that he was running both of his air's on his older 5th wheel( no power shedding but he did turn his appliances over to gas). I listened for the compressors to kick in, thinking surely the pedestal breaker would trip but it never tripped..I can't explain it, just reporting what occurred, nothing more. My first thought also was a faulty breaker but after monitoring voltage and lack of over heating of the dog bone....I didn't have my clamp on amp meter with me but will take it along with me next month when I return their. My built in meter's have the ability to measure amp usage ....but the amp feature hasn't worked for some time. .
My final thought was that since the park was not busy, I was getting full power without the additional draw created by hundreds of airs switching on and off. Once again, normally I wouldn't think of trying this because I do have some understanding of start up amp's required and continuous load. One other thought...something that just adds to my curiosity...TT parks are not known for their state of the art upgraded pedestals....they generally use the bare minimum with little to zero maintenance.
