During the heat of a hot summer day, we will turn on the generator in order to run the roof a/c while driving down the road. In the winter I take the PC out every three to four weeks and drive it around for about 20 miles for its monthly workout. It heats up the engine, warms up the tires to keep them from dry rotting and keeps my driving skills up to date. During this drive I run the generator and the roof a/c's heat strip. Everything gets it work out at once. Running anymore often than once a week is over kill in my opinion, every three weeks does the trick.
Thank you, Tom. a very helpful answer. I was really hoping I could run both at the same time. Neither system gets short-changed in its workout.
I was following a workout plan similar to yours, every 3-4 weeks, planning to go on occasional overnight jaunts. I (like a few other folks, I suspect) was totally unprepared for this arctic winter blast. This isn't supposed to happen in this part of Oregon, maybe 1-2 nights in a row of below freezing. But this is forecast to last for several more days. (The news this morning reported that this is the first time in a very long time -- if ever -- that the entire state was below freezing. Even over on the coast!) So depending on road conditions, for the next week or so I'll try to go out every couple of days and give it a run. Just for my piece of mind.
