Default Depends on the TV (the Alternator and ECM)

On your Tahoe, or my 4Runner, there is no problem at all: When running my system at full power (about 280W into the batteries, a bit more than 300W from the Alternator)... the Engine Control Module (ECM) raises the RPMs when idling, by about the same amount it raises the idle RPMs for Air Conditioning. On the road, I can't tell any difference.

But, in my old Subaru Tribeca, it would be an issue, and it would need an alternator upgrade. I have done an alternator swap on that vehicle - it's failure prone, just from running the engine, ventilation fans, stereo, headlights, and other accessories. We don't tow TM with the Tribeca.
