I don' park my truck without putting bait out for rodents. .
I change or have the oil changed every 10K miles and will change fuel filters every 30-50K miles... I've installed a 10 micron and a 2 micron filter system and date/mileage each filter with a paint stick upon installation... to date, we've not had a filter plug up and this truck still has its factory fuel filter.
At least once a year, we give the truck a once over and now that's turning to 2 times a year now we are much farther from home... when we leave for AZ in Sept we do the safety inspection and when we leave for WA in April we do it again... its a front to rear inspection, fluid level, fasteners, battery water level, coolant recovery, UJoints, lug nuts, brakes. . . . etc...
And the list goes on... .
