I've tried to run one of my rooftop A/C units using a "regular" (probably 14g) extension cord, with predictible results (the cord got hot, and there really wasn't enough power at the coach to reliably run the A/C). I was recently camping in Mexico, and one of the campsite residents said he had a "30 amp cord" that he'd hook up to my coach so I could use my A/C. After he hooked it up (I was elsewhere), I flipped on the A/C and it worked great. Only later did I notice that the "30 amp cord" was a "regular" though thicker, three-prong extension cord. Seemed to work just fine - the A/C ran for five days without anything getting hot.
My question is - what gauge extension cord have you gotten away with on a 25' or 50' extension cord (running one original A/C unit)? I'd really like to get a three-prong (non-twist-lock) extension cord since I don't have a 30A outlet anywhere near where I store or work on my coach, and it would be nice to have A/C when working inside the coach (hey, I live in Arizona!). Yes, I know a 30A or 50A cord is better, but I'd need a really, really long (and expensive) cord to make that work - I'd never be able to put it in the coach, either... a 50' 10 gauge cord would be about the max I have room for without giving up storage space for something else.
