I need help from Forum members who have knowledge on invertors on which model to select. Thanks.
The Honda 2000 Companion puts out the same 15 amps of power that the Honda 2000 puts out. What's different is that if you purchase both the Honda 2000 AND the Honda 2000 Companion and connect them together, you can get 30 amps through the 30 amp plug on the Companion. If you only have the one generator, either one, you will get 15 amps. BTW 15 amps is an approximation and depends on many factors.
The Honda 2000 will run the Air Cond on my 2014 - 19'. I haven't tried it in real life at a high elevation but it will run on my driveway at 200' above sea level. The higher you are, the less it will perform. The generator also needs to be out of eco mode. I've tried two Honda generators: first my neighbours, and then I purchased one.
The Yamaha 2000 generator freaked out my EMS (Electrical Management System - over and under voltage protection). It did this even when the EMS was disabled. When the EMS is disabled it still protects against surges. For some reason it sensed surging power from the Yamaha generator and shut out the circuit. The EMS manufacturer rep (Progressive Industries) indicated that they have had trouble with the Yamaha in the past and urged me to try a Honda. Progressive also notes that their device is not intended to operate on generator power. It may not be Yamaha's fault, but chances are that if you've got an EMS, the two won't play well together. I think some other people on the forum have had success with the Yamaha 2000 but they may not have had the EMS or maybe something has changed in either product. A larger Yamaha may work just fine.
With 2000 watts you'll be able to charge batteries OR run the Air Cond, but not both at the same time. Don't see why you would need both at the same time anyway unless you don't have solar. If its hot enough to use the AC, there's probably enough sunlight sometime during the day to juice the batteries with solar.
