2x100' 10ga extension cord + 25' 8ga cord + 25' shore power cord. Used at my camp for many years until I could get service installed at my pole barn and RV. I used only one appliance at a time, like a space heater or microwave. Never the AC. I even turned off all lights to use the microwave. Never had a problem.
Our RV has 30 amp service. We have the following cords:
* ~20 foot #10 gauge shore power cord
* 25 foot #10 gauge extension
* 100 foot #10 gauge extension
We owned the RV for years before buying the 100' cord. The reason was that we were visiting relatives in Gilbert (Phoenix area) and not only was it over 100*F, but they had just had monsoon rains, so it was HUMID! We could have stayed in their house, but one main reason we bought the RV was to avoid that. The outlet was on a 15A circuit. I wasn't sure if it would be able to handle the A/C for an extended period without tripping, but it did. We have a Progressive Industries EMS with a display, so I was able to monitor the voltage and current. The lowest the voltage got was 109V, the max current was 12-13 amps. I can't recall the no-load voltage, but it was pretty decent, maybe 118V. As it cooled off, the current draw dropped to maybe 9-10A, and the voltage increased.
In short, the 100 foot #10 extension + the factory shoer power cord (~120 feet total) worked well -- but that was a max load of 13A. Much more and the EMS would have cut the connection (low voltage cut-off is about 107V).
We've never used both the 100' and 25' extensions together. In fact, the only time we use the 100' cord is when staying with family and friends. We've almost never been to a campground where an extension was necessary. We may have used the 25' extension once.
Our watchdog reported 99 voltes ….as the entire campground plugged in their electric heaters one chilly night in desert hot spring Ca…it had cut us off at 117……
But to minimize voltage drop when I am a little more further front the pedestal than the reach of the internal cord. I also carry a 10' 30A extension. Very usefull when 25'is too long. And all my standard 15A extensions are 12 awg.
One 25-10awg and two 50-16awg, but light load. My protection box will shut off at around 110V or so, I forget the exact spec. That happened at a campground run by a diesel generator with extremely variable loading and poor output regulation.
(My box also shut off another time at 135V, same visit same site.)
100 ft 16ga extension cord. (They should not even sell these) I was just trying to run a 50 amp battery charger. Cord got hot and charger did not work. I knew better but it was an emergency situation so it was this or do nothing.
35 Feet. I had a decent size class A and do not know how long that cord was (assuming 25') , but I also carried a 50A-10 foot extension. I was full-time, and surprisingly, I think I only used the extension less than 5 times. It never got hot.

Extension cords over 25ft should be REQUIRED to be oversized. 30A extensions should use #8 wire. Try finding one, however, at ANY price.

Of course I carry a 25' 30A extension for my TT.

Mike,
Enjoy your videos.
Feel free to correct this
Voltage drop formulas helped me. Its geeky but Educational
Basic Ohms law - V=I x R I=Current(amps) R=Resistance(ohms) or
(V_{drop}=2 x I x R x L L=Length of cable
Wire gauges have different resistive qtys - Lots of charts showing this - Google
I have only had to extend my power cord once. At that time I used a 25-foot extension that was as heavy as my power cord. (It came with the rig.)

Yeah, I’ve done pretty much the same thing.
We only use the 25 foot cord that comes with the RV and a huge watchdog. EMS surge protector
