#4 If you boondock in remote areas for weeks at a time, don’t make daily trips into civilization. Go to your camping spot with supplies to last a week. Do a supply run (paired with fun town activities, if you like) at the end of the first week, and get enough of everything to last until you’re ready to move to your next destination. You’ll save money on fuel, and you won’t have as many chances to make impulse purchases.
