A few weeks ago we took delivery of our first Class A, never had a generator in any of our RVs before so wasn't sure...We have been volunteering at a NASCAR race twice a year for close to 15 years and have a place to park within the track with 50 amp service, however this year they have rented 3 travel trailers to accommodate others and told me we were welcome to still bring our Class A but would not have shore power but could run our generator.My question is, we will be there for 4 days and was not sure how long we could continuously run the Onan diesel generator? Fuel will not be an issue and I am sure we will shut it down while we are away from the Coach. But is there a "too long"? How many hours could I run it?

They are made to run and run and run. You can run it the whole time you are there if you want.

They are designed to run 24/7. As long as it's in good running order and maintained it can run continuously for thousands of hours.I would try and make sure it's vented above the roof line. A genturi might be a good investment. Nothing to do with the gen running mechanically, just safer and considerate of those around you.

Great. Good news. It was serviced by the prior owner at Cummins / Onan shop and again by the RV Dealer we purchased it from. I have all of the service tickets.It only has right at 700 hours on it now, so we will see how it does.Thanks

You can run it 24/7 if you like. Just make sure you have the oil level and coolant level checked, before you do. Also give yourself between 1/2 to 1 gallon of fuel per hour while you are running it. You might also want a Genturi exhaust pipe so you do not gas your neighbor's out. Have herd several tracks require them.

Make sure you keep a eye on carbon monoxide if you or nearby rigs are running Generators a lot. Your rig likely has a detector - make sure it works - you can buy a portable battery powered one for about $25.
