Air Mattress: While an air mattress isn’t strictly necessary, you are going to want to make your car as absolutely comfortable as possible, and this goes a long way. It makes your bed about two feet wider, much warmer, and softer.
Sleeping Bag: This is for cold weather sleeping. You can stay in your car warm and snug, and watch the snow drift softly to the ground.
Blankets: These are for the hot days, the days when that sun just won’t stop (not that we’d complain about that!) If you don’t use them to cover your body, you can use them to create shade.
Pillow: Whether you choose a neck pillow or an ergonomic pillow, be sure you’re not going to be sore every morning when you wake. Many of the pillows at the link deflate, making them easy to store.
PJ’s: Something comfy to sleep in that you can also walk around in, for things life bathroom runs, and security checks. Here are great options for men, and great options for women. If living with children as well, here are some options that will keep them cute, cute, cute.
Propane Stove: Small compact propane stoves are easy to set up in parks, parking lots, and even on the side of the highway.
Minimal Dishes: You aren’t going to want a lot of dishes rolling around, and no glass. This compact set should meet all your needs.
Wipes for Cleaning: no running water means everything gets wiped down right after use. Clean up is a breeze!
All in One Kitchen Tool: This is good for everything.
Pan Set: Small, portable, very useful!
Pot Holder: You will need this for everything, from pouring water to cooking eggs. I like the flat ones for easy storage, and they can open tough jars!
Folding Table: This is optional, but makes cooking on the side of the road or in a parking lot much easier.
Electric Converter: This option runs off your battery, and is great for charging all your electronics, especially while you drive.
Solar Panel: This is independent of your battery, and is strong enough to charge your electronics. This is recommended by top campers, and full time travelers.
Tire Changing Kit: Be sure this is adequate for your vehicle, but it is a necessary tool.
Car Tune Up Kit: This needs to be done every few thousand miles, to prevent engine wear. It will be specific to your brand of car, but the link takes you to a page that will show what I’m talking about.
Sunscreen and Privacy Mesh: This makes your windows darker, and allows you to see out. No one can see in this way!
Personal Safety Alarm – recommended by the Today show as a must have for travelers. Warning, keep it somewhere near your sleeping area and be sure to keep the battery strong.
