It's no accident that Generac has just kicked off a very aggressive marketing campaign.
I have installed a few gennys, and not a one of them was a Generac. Indeed, all were specified by someone else; my opinion was not asked for.
I am given to understand, from those with more direct experience, that this brand has a poor track record. I am told that the company has a very one-sided 'dealer' contract with EC's, and require they you stock lots of unique spare parts.
You are quite correct is suggesting that the genny itself is perhaps the least critical part of the install. The muffler is critical; most sets run with a roar that will wake the dead. The exerciser, load bank, and transfer switch are critical components.
