Having been to this movie before....
I had a 2400is, and a coleman mach III (circa 1999) which was much less efficient. Once I put the supco hard start kit, I was able to start and run my AC without a problem. I was able to run it at sea level up to 6500' and it had enough to run it.
What I didn't like about my 2400 was two issues:
Weight (75lbs)
No ability to disable ECO mode.
When I sold my TT for my 5er, I sold the Genny and switched to my honda EU2000.
My EU2000 with a hard start kit installed, and with ECO off, and with all the other "stuff" switched off (fridge, converter, etc), will start and run my AC at sea level, but if it's really hot (over 90 degrees) or at altitude (3000' or higher), the 2000 will overload after 20 minutes (which is the maximum it'll put out 2000 watts).
All in All, I'm ok with my 2000, but eventually I'll purchase a second one to allow me to run my AC when I really need it.
You MUST run your FAN for your AC (not ac running just FAN on) for about 5 minutes - and with the FAN switched to ON, switch the AC to ON. This allows you to energize the circuits and the load is only the Compressor - not the fan and compressor.
If you get your AC running, set the temp as LOW as you can and don't let it turn off. Otherwise, it may not restart.
You also need to be sure your dogbone adapter is equal insize to your power cable from you TT. If it's any smaller, it won't have enough capacity to move the amps needed through it. I had what I thought was a decent dogbone, (120 20 amps to 30 amps RV) and the wiring internally while not visible to my eye wasn't at least a 10 gauge wire and it restricted the flow of electricity. Which I Switched to a dogbone that was direct (female RV to Male 20amp) it worked.
