Generators: A/C units and sequencing

Hello - I suspect these 2 questions have been asked and answered several times, but I haven't specifically come across it yet - so here I go!
I am a first time TT owner, and trying to figure out
1) will a 2000 watt Honda generator run an A/C unit? One that is like 13,500 BTU? Or maybe 15,000 BTU? All the RV dealerships tell me I need a 3000 watt generator, but I have a friend who swears that a 2000 will do it...
2) Can you sequence a 2000 and a 1000 watt generators together, to then run said A/C unit? Maybe this is a cheaper option?
I'm wondering if I should get the 2000, which is much more in my price range, if we 'think' it will run the A/C most of the time, with not too much else running, then obtain a 1000 if it doesn't cut it?

I have heard that some people match a 2k and 1k together. Honda says no, so you would be on your own if something bad happened.

Nope and Nope is a good answer.

Honda makes a connection for 2 2,00 watt units that matches the phase of the generators but I would question if that would match 2 units of different sizes.

If you were to attempt to run "JUST" your AC on a 2000 watt unit you would be right on the edge. You would have to turn the convertor off and put the frig on gas and still might have trouble starting the AC or even doing damage to it.

We ran our 13.5BTU AC off a Yamaha 3000watt. We had trouble starting the water heater or the microwave without overpowering the generator. Once we upgraded to a 15K BTU AC it was all over. We now run off two Honda 2000watt generators linked together.

My advice; go with a 3000watt generator at the very least. Bite the bullet and camp comfortably.
