Best Generator size for small (23') Travel Trailer

If you have a 23' TT, what size is your AC, if you have one. If it's a smaller, less than the standard 13,500 one I have on my FW, a Honda or Yahama 2000 should be able to start and run it, I would think. If it's the 8,500 AC, then certainly the Honda or Yahama will be able to start and run it. Might not be able to use anything else at the same time, but judicious use of each of the electric items would make it work.
