First, welcome to the group. We will try to answer your questions and some of the answers may even be helpful.
The short answer is "no" on most coaches. A few coaches are set up to run 1 or maybe 2 roof airs from the inverters, but the general view is that running the generator to run the roof airs is the way to go. Less of a load on the inverters, alternator and engine, and it exercises the generator. Most gennys never run enough or under enough load. I am at 4000 hrs on my generator and it runs great. I never hesitate to run it to work the roof airs.
