Our '03 CRV is fine when pulled all day, without pulling any fuses. Left overnight and pulled a second day is another story. That lesson learned, we generally fire it up and let it run for 15-20 minutes while we're setting up camp for the evening, then do the same while breaking camp. We've gone on that schedule for a week straight. Oh, and we do carry a battery charger with us in case we screw up again....
I think it's the newer cars, especially those with Nav. systems that need to have the fuse pulled.
