Running a generator to exercise it when there's shore power?

Didn't the dealer tell you to do that at least once a week. Shame on them! I do mine daily when I'm camping. Keeps them in top shape.

Some folks would argue that the sky is blue on a sunny day...
And adding hours to an infrequently used piece of equipment (if it was frequently used you wouldn’t feel the need to excercise it, right) is about the silliest argument for not doing it. And the math is off unless you have your RV for 150 years, lol.

I like this idea a lot.
If we were to "exercise" the entire RV - Say 2~300 miles and a full over night at least once a month, then you could be very sure that it was ready when you want it to be. For those of us in the north, that means winterizing the potable system monthly, oil changes more often and driving over salted roads many more times than I like.

Small problem, that would have added close to 600 hours on the generator by now.

Maybe I'll stick with putting her to bed for the winter. Doing a proper fog job and disconnecting all the batteries.

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 !

I try to remember to run my home portable genny every month or so. It is a noisy cheap open frame type kept for hurricane loss of power backup.

If you are going to make noise, go big but make it as short duration as possible. Sometimes I will combine genny running with grass cutting. Sounds like I have two mowers on the go.

Wheel it outside. Start it up & plug in a couple of 1000w heaters to give it something to do.

I'd rather exercise my genny monthly and know it's going to work than find out I have a problem when I really need it. All this doom and gloom about problems it causes by those of us that exercise them monthly is gibberish. It doesn't take a ton of common sense to know that running any mechanical engine frequently is far better than not running it for long periods of time and there is far more evidence behind that than the few who claim running it too frequently causes more problems than it solves. Luckily there are very few people who fall into this category who offer such advice. That is not to say that a genny can't be stored for long periods if certain things are done, like draining it etc. But I'd much rather have a genny that's periodically exercised than one that sits dormant. That's usually the advice that engineers will offer and they don't all have a hidden agenda.

Truth.

Agreed.

. Wheres the harm? whats the consequence? When mfgr. builds in monthly auto start to exercise for a home propane unit, doesnt that have a n alert to genny users that if you need it on demand, you can depend on it.

I disconnect from shore power while test running genset. You must test run under load.

Simply turn off the breaker and start gen. Let it warm up a bit then turn on AC or something to place a load on it.
