Clean your car before and during your trip.
Go ahead, leave the napkins and gum wrappers under your seat. Leave the receipts from your last business-related drive in the glove box. Don't sweat the dog hair in the back bed ... but you'll be sorry. A few days into your trip, when the old gum wrappers are joined by new fast food wrappers, when the glove box starts overflowing with hotel receipts and local maps, when dog hair starts sticking to your luggage and your gear, you'll rue the day you failed to pull out the Shop-Vac.
