I have the Yamaha EF2400. Mine is about 5 years old and never a problem. I love it, but...If I had to do it over, I'd just go small, give up on the A/C and gain the convenience of lightweight.
Again for the umpteenth time :R - ditch the larger, heavier genset, equip the A/C unit with a soft starter kit such as the
Micro-Air Easy Start Soft Starter Kit, and instead use a smaller, lighter genset such as the Honda EU2000i or Yamaha EF2000iS to run it.
As for the Progressive Industries / Yamaha disclaimer it addresses just the original EF2000iS and no other model, including the newest version of this particular genset, the EF2000iSv2. Powering a trailer protected with a Progressive EMS requires that an inverter genset's floating neutral output be G-N bonded and as was the case with my own EU2000i this works just fine. However, if I were instead intending to use an EF2000iSv2 I'd first call Progressive and ask whether that warranty disclaimer still applies to this new model. If so, or if there's any doubt as to which Yamaha model this may or may not apply, then the solution would be to make sure the EMS is completely out of the circuit anytime a Yamaha genset is being used as source power, reserving the EMS solely for those times the trailer is connected to shore power.
