I recently purchased a Lance camper that included a LP Onan generator. Reading the manual, it states to run the generator once a month for two hours to exercise it. What is everyone else doing? 2hrs seems like a long time. I would think it would be better to either run it once a week for 20-30mins to keep things lubed or to squirt oil in the cylinder and winterize the thing. What works for you? I don't want to have it go bad from sitting but seems a lot of hours are put on in the driveway.
