http://www.walmart.com/catalog/product.do?product_id=3657606Are you going to be camping? You didn't mention a tent that I saw. If so, bring along an extra tarp you can make an a-frame or lean to with. This will give you a place to sit outside of the tent but out of the rain and sun.
re: your laptop: Alot of truck stops have WiFi these days, as well as Hotels, McDonald's, etc. Good way to find campgrounds, check weather and road conditions, or stay in touch with loved ones. You may need a credit card to access some of the wireless networks.
Consider getting a prepaid Visa or Amex.
Your truck supply list didn't have anti-freeze and water. Carry a gallon of antifreeze, and 5 gallons of water. You may need the water for yourself in a breakdown situation.
Security:
I didn't see a flashlight. Let me suggest a small lantern + a flashlight. If you're changing a tire on a backroad at night, the lantern will give you better light than a flashlight. You might consider a small headlamp in addition.
Never whip out your entire wad of cash. Either use ATM's along the way, or if you're carrrying several hundred in walkin' around money, put only what you need into your front pocket. This way when you go to pay, you're only paying with the minimum amount possible. This keeps thieves from seeing you with a few hundred dollars.....
How are you tracking your expenses? let me suggest you build a spreadsheet or keep a ledger. When i was 19 I went on a week long road trip with two other guys. One night in the strip club and we were suddenly broke. Only thing that got us home was my CC.
Budget out what you think you are going to need per day, and how much you have to start. Track your expenses closely by keeping reciepts and tallying at the end of the day what you spent.
Sounds a little anal for a road trip, but it beats begging mommy for money when you're in the middle of BFE.
Don't call anyone "Good Buddy" on the CB.....it doesn't mean what it used to.
How are you carrying and securing all this gear?
I'm a big fan of the rubbermaid totes. Stackable, rainproof, and they form a more or less flat surface other things can be laid on top of. Great in a car, SUV or camper shell. If your truck has an open bed, you'll want something you can lock and lock to the truck. Thieves will steal anything. An actionpacker can be locked, and with some creative drill work you can run a chain or cable through it.
I'll think of more later, but I'm off to the throne room now.
Jfruser's method of pooping works, but there's simpler ways out there.
