Volts and amps are the two sides of a teeter totter.  Watts are the pivot point in the middle.

I've been a wire-wiggler for a long time and have often struggled to give an analogy of Volts X Amps = Watts to my wrenching friends.  (let's not go into power factor!). Your explanation is great!  May I use it?

I've finally figured out that torque X rpm = horsepower. Sort of. So then a gear reducer is a transformer.

By all means use it.  I am surely not the first to think of it, but it just came to me when reading this thread.

In any case,  now that the electrical miracle is ruled out,  there is no benefit to using a 240 rooftop.  It will only complicate life.  We used to run an AC on a 3500 w. A good 3000 may do it too,  but it is good to have a bit of reserve.

Scott -  don't do it.  I've got 240v AC and already we are feeling the complications/limitations of using 240v.  Add to the fact that its 50hz and your just complicating things.

It would be one thing if it was a super pizazzical AC unit that cooled the entire coach with exuberant features but if its just saving a few bucks to use something that's available it might be more trouble than its worth.

Just a note here, if you are looking to use a small generator, the Honda 2000's can be put in tandem, so you can use one or both depending on your needs.  There would certainly be enough power for one AC with both, while using only one for smaller things like charging batteries.

Thank you so much for the explanations. Love reading every one of your responses. Love the teeter totter example. Ok, so now that I've figure that out, I won't consider a 240 volt model. Sean confirmed by personal experience that it can be a pain.
