Two honda generators in tandem

Yea my first generator - the 2000 watt honda i bought a year ago falls in the serial number series. Something seems wrong although - the 16 to 25 percent loss from altitude is significant.
I was also thinking the cord from one to the other generator could be faulty? The cord from my trailer to generator is fine or at least very unlikely the problem.
Both generators the eu2000i and 2200i companion are both new with less then 10 hours on them.
The trailer is new and the ac seems to work fine. The generators bog down and then hits overload after about 3 to 5 mins after i turn on ac. It may be the generator that the trailer is plugged in to (the companion) that is the only one overloading. I was just thinking about this and will have to watch to see if one or both overload.

something is definetly amiss since it overloads after 15 minutes or so. what I do know is that a single honda 2200 will RUN an dometic 13.5K or coleman MachIII all day long at 7,000ft altitude without overloading. Brother and I have done so. The trick is getting it started, which is easy with the micro air easy start. The easy start reduces starting current, but once started doesn't affect the normal current draw. So 2 honda's shouldn't be any issue. Either there is

1) an issue with the generator(s)
2) they really aren't paralleled, but again one should be able to keep it running
3) you have additional draw.

Now, if your converter is still on, which it WILL be unless you turn OFF the breaker it is on, AND your batteries are drawn down AND you have a good charger (not a WFCO), then you could easily be overloading the generator. A reasonably discharged battery bank and a good 60A or so converter will draw as much or more current than the AC, 12A or so. Then the combo could cause the generators to go into overload after 15 minutes or so.
