While you're at it, check the 20amp breaker on the genset, as it sounds like it's off or tripped and only feeds the rear air. As for other things plugged in to various outlets, they are a separate load in themselves and yes they can draw more current if the voltage is low and produce more heat than normal.
Thanks Trop. It's a new vehicle for me and I'd never taken the cover off the Onan. Indeed the 20 amp was tripped. I can also see I'm losing some oil in there are additional concerns- with 250 hours on it I figured I might have another couple of hundred before doing much but I'll now be "spending some time" with my generator this weekend!

Either way.. Voltage may be the problem Press the V button on the Kill-a-watt and report the display.
NEXT is frequency. Many of those small electronic devices are kind of particular to frequency.. Press the Hz button on the Kill-a-watt and report the findings.
Some devices if the Hz is off.. can get very hot.
Wa8- The AC voltage is in fact running between 116 to 118 (more when the AC units are lit up) while the frequency seems safe at a pretty steady 62 hz.

Low voltage from the generator? I don't have an ONAN...but do have a 5500 GENERAC, and the owners manual shows a board with an adjustable screw...for voltage.
Jersey-
I'm heading to the Onan website to see if there is an adjustment I can make to bring that voltage down towards 110. It will also be a good time to find out how many hours I should be running it between servicing it-
Thanks to all for all your help- the second AC will come in handy when I'm boondocking on the edge of Death Valley in a few weeks. Do the AC units on the roof have the same LP fittings for adding propellant that I do for my truck? The rear unit seems a little weak compared to the front and I'd like to refresh it.
