Welcome aboard! Yes, we are ALL still learning - that's the nature of RV'ing in general, and Thor's specifically :-D
Per generator - as long as you have good exhaust and ventilation, running the generator while driving will present no issue. Depends on your power needs. If it's hot, and you "need" the coach AC running - you can do so. Same for refrigerator if you're low on propane; or have to turn propane off due to tunnel transits.
Just remember that will cut into your driving range proportionately.
