I would not go less than #10 gauge. The problem you will run into is the momentary inrush current which can be quite high. If the wire size is too small, the AC may not start. You could consider installing a hard start capacitor or the Dometic Smartstart (expensive) but probably not worth it for a one time event.
Here is one thread for example that talks about AC unit inrush current. http://www.accuride.com/Woodworking/Product/Details.asp?ProductID=63&CatID=&ProductName=Woodworking-9301
If you have a detachable shore power cord, you can connect two cords together with a generator adapter which are inexpensive. We've got a spare 30 amp cord as a spare and if we use the adapter, we can make 50'.
