Hi Alex,
It's Rochelle here. I posted a picture of all of our items before we left at the this blogpost:
http://ramblewriter.com/ramblings/?p=154 (which is also attached to this post). Most of the items are labeled. However, we added a few items before we left the States, such as:
-- 3 water containers that were stored on the roof rack
-- 2 gas tanks were also stored on the roof
-- Our food bin is not shown here - it is about the same size as the kitchen equipment container.
-- Our medical kit increased in size
-- Nick's tool bag is not shown in this picture
-- We stored a car jack in our bottom storage space as well
For Organization:
The covered plastic storage bin that holds our kitchen equipment worked very well. We also traded the black bin you see in the picture for a metal mesh container that was almost exactly the same height as the bottom storage space (this seems trivial, but will be very important over the course of several months!).
I would strongly suggest that you take enough to only fill your bottom storage compartment. It is important to keep the back of your truck (the top portion that can be seen by outsiders) fairly organized and uncluttered to deter thieves. Also, you are sure to pick up more equipment and stuff along the way, so you might as well be ready for it
And a Few Thoughts on Saving Space and Clothing:
-- Keep the clothes you bring at a minimum, and only bring items that can layer / be worn with any combination of outfits. My silk long underwear worked wonders in cold weather, which was much smaller to pack than numerous sweaters, etc.
-- My only pants were: 1) my cargo pants 2) exercise pants which doubled as "fancy / going out" pants 3) a pair of shorts with multiple pockets 4) a pair of light pajama pants.
-- Buying extremely light, fast-dry underwear will save you a lot of drying time in humid climates (think Central America).
-- Hiking boots and my black Mary Jane Crocs (see Travel Gear posts) were my only shoes
Nick will need to answer the question about the 4Runner size difference, but I hope this helps!
