I am How does the Cummins Onan QG 5500 - 5500 Watt Evap Commercial Mobile Generator compare to other generators out there?

My name is ***** ***** I am going to assist you with this.
There are several things that will cause a VR to blow like that - bad brushes/slip rings create high resistance in the field windings, a bad quad winding in the stator can cause a VR to put out too much field voltage, loose wire/dirty connections can create high resistance.
You didn't specify what model your 7,000 is. If it is an NHM series, I would definitely rate it higher than the HGJ series (what you call QG). The NHM is much easier to troubleshoot, and to me is a more reliable unit.
