So my opinion for what it’s worth is to do whatever you personally feel is best for your particular wants and needs!
In my case I have a 1998 Rig with the originally installed generator which starts and runs perfectly whenever it’s been called upon ,
I do not have any particular schedule but do excercise it a few times each year! It’s an Onan product quiet diesel 7.5 Kw unit.
My next door neighbour installed a very expensive 20 Kw Generac unit in his house which runs on propane and is programmed to start up every Tuesday at 10 am and runs for 20 minutes! It is located inside a specially constructed shed but still is noisy !
So after only 7 years his Genset stopped working and was determined to be unrepairable! He replaced it with another Generac unit!
In that 7 years we experienced 3 power failures in our neighbourhood and only one was for more than a few hours!
Now maybe my comments don’t belong here and I know very little about generators but it seems to me running one every week is a tad excessive and must have contributed to the early failure !
