We have a 2003 Honda CR-V with over 165,000 miles and all we do is run it through the gears as recommended and make sure everything is off. We always start it up for a few minutes at rest areas every 4 hours if we will be towing a long day. We never had a problem until the car was maybe 8 years old. It was dead every time. It was then that we realized we were still on the original battery ??. Once we replaced it we were back in business again, no problems since. Now my husband is working on setting up our 2003 CR-V for towing.
