I'm pretty sure that published weights do not include weight of options. In the case of a generator option, you also need to consider the weight of the 'Generator Prep' option which includes insulation and shielding to keep noise and more particularly fumes from penetrating the living space. When I checked into adding a generator to my front storage, I was shown storage bin lining that is basically an aluminum box that seals the bay. Also added was an exhaust pipe. Sorry, but I didn't ask what the weight add was. If you know someone with a front installed Onan, perhaps they can tell you what the pin weight add on was.
