I'm with dupreet (and others) in that the $100+ you'd need to buy the 10 ga wire to do this would far and above exceed any gas mmoney you'd spend on your own generator. Oh, and I wouldn't guarantee it'd work, given afore-mentioned voltage drops.

We're doing 4 contests this year plus 1 in october that I don't plan on needing AC for. So the gas will add up. I'll see how close I get to the connection. I do have an extra 30 amp wire to extend my RV connection. From what I'm reading the adapter my get fried though..... I bought the generator for bbq and the house so I recon I'll use it for what it was purchased for (some contests only provide 10amp service).
It is really very simple, try it. If the voltage INSIDE the RV with the A/C running is at least 110 VAC, you are fine. If it is less, don't run the A/C. Note voltage may dip lower for a second when compressor kicks on, that is ok.

Agree with 10 guage extension cord. Helps reduce voltage drop. Using your 30amp cord is good but keep the length of total cord to a minimum. Yes. Get a voltmeter, like Kill-A-Watt. Watch it. I do not like mine to go below 110v. I know 108v is safe but at 108, I would have to be staring at it in case it dropped some. One of the problems with the spider is that others are drawing power as well. I would take the generator and gas as well. If the power drops, go to your genny. It might be expensive to use the gas but not as expensive as repairing/replacing the AC.

Saw an interesting A-Dapter the other day. It had a 30A male plug and a 20A male plug wired to an outlet box with a 50A female socket in it. With that, you can get 30A on one leg of your 50A shore tie cable, and 20A on the other side. Not as good as 50 + 50 on a 50A circuit, but better than just 30 and you don't have to run another cord.

Everybody talks about 20A plugs, but it should be noted that the common household outlets that most of us have in our homes, garages, etc. are in fact 15A outlets. A true 20A outlet has the flat blades perpendicular to each other rather than the blades parallel, as in the 15A outlet, as seen in this diagram:
The NEMA 5-15P is the standard 15A outlet found in homes; the NEMA 5-20P is a 20A outlet found in circuits fed from a 20A breaker. Most 20A circuits actually use a combination outlet that will accept both types of plugs, but if the outlet only has parallel slots it's a 15A outlet, not a 20A outlet.

Thanks Mr. Hepburn for posting that information. Should also point out that most 12 AWG extension cords are only rated for 15 amps as well because the plugs are only 15 AMPS. That being said, I run my AC at home off a 20 AMP circuit with my trailers cord and a dogbone with no apparent heating and little voltage drop.
