First and most important tip -
Take half the clothes and twice the amount of money you think you'll need.
Check Darren's set up for
living out of a 3rd Gen 4Runner for weeks at a time. I know he pulled his passenger seat out for
one extra long trip to Canada. If you're not gonna need it and have a place to leave it, remove it and you just opened up some extra storage space up front.
Bring the smaller cooler. Ice, food and drinks are available everywhere. Speaking from experience, it's much easier to pick up a few things more often as you go, than to have a huge cooler to pack around. Just about everyone that sells gas, sells ice too. I would apply this line of thinking to big 40# bags of dog food too.
I prefer packing in soft duffel bags as opposed to hard sided boxes or totes. I find duffel bags easier to move, stuff, pack and work around. Plus duffel bags don't rattle and vibrate or rub up against something else.
Regarding power for cell phone and a laptop; you could invest in a power inverter based on your intended useage. I went simpler and bought a
3 hole adaptor for the cig lighter. The 3 hole will allow for simultaneous charging of a cell phone, laptop, radar detector, Sat Radio, whatever you have. Then add a
Micro Inverter, to plug your laptop into which plugs into your 3 hole adaptor. I've run this set up for several big trips on the road over the last year and experienced no problems. Quick, simple, cost effective and no additional wiring labor necessary. I would make sure the 4Runner's battery is on the newer side.
Roof racks or hitch rack? Roof rack everytime. Less of a worry in parking lots and when you're not with the vehicle. Deviants can quickly grab your gear off a hitch rack, most won't make the effort to pull something off a roof rack. I would make a few attempts at packing the Runner with what gear you have before investing in a rack though. See what kind of space you'll really need. Ideally, fuel and a second spare tire would go up top only. If you do need more personal storage, the previously mentioned cargo box would be ideal for a secure and aerodynamic solution.
Spare parts? I seldom bring them and surely not enough to rebuild the whole rig. I figure if I break down on the road and it can't be patched or temporarily fixed, someone will be along soon who can give me a ride to someplace that can help me fix the problem. This is North America afterall, not some third world jungle. And that's when the flavor of the trip
really happens anyway. It's personal preference, but I prefer not to load down my Toyota, sacrificing weight and space with spare parts that I'll likely not need. Spare belts, hoses, duck tape, JB Weld, fluids, handtools and fuses should be on board.
Recovery - straps, shackles, hi-lift and a come-a-long. If you don't have a hi-lift, you'll need a jack big enough to lift a 4Runner with a 4" lift & 285's, off the ground. I like the looks and weight of the
ARB Exhaust Jack myself. Pricey but lightweight and easy to store. I wouldn't worry about a winch. If the trail looks beyond your skill or your 4Runners ability, turn around and find another trail. Why risk it when you'll be alone? I've seen plenty of this country without a winch. Probably more than most of the people who own a winch. Don't fall for the
must-have-it hype, cost and weight.
Odds & ends -
1. Invest in a quality first aid kit, maybe one for your dog's special needs to.
2. Bring a notebook to document your spending. Start with your total amount and subtract each day. I found this made me more aware than just logging,
"$50 in gas today, $10 in food, etc...."
3. Bring lots of batteries (double A's, triple A's, 9 volt, whatever your stuff requires). They seem to go fast or disappear on me.
4. Bring books to read. Even with a pup, camping solo effects the mind in funny ways. Having something to read, helps.
5. A headlamp in camp is much more user friendly than flashlights, but carry both.
6. Buy and bring a fire extinguisher, every vehicle should have one.
7. Pick up a
decent air compressor like the MV-50.
8. Get a camp toilet chair thing. Trust me, the stomach never erupts when it's convenient. Don't forget the TP.
9. Stock up on travel size toothpaste, deodorants, asprins, Advil, shaving cream, hair goop, whatever you use daily. You want the comforts of home but smaller.
10. Maps are the windows of the world. Bring lots of them.
This is what I can think of based on my experiences with multiple month-long adventures. You will likely need less stuff than you think to enjoy yourself. Be flexible with your schedule, take your time and savor the trip.
Best of luck to you on your journey - :beer:
