Packing all depends on the length of the trip. Short weekend, and week long trips don't require as much as a few weeks. We have a full length sleeping platform with more than enough storage a simple overlanding trip. When we start talking about spending multiple weeks out, and the need for random gear it's not quite enough.
Full length platform with dual drawers. The draws hold all of cooking supplies, cutting board, plates, bowls, mugs, french press, skillets, pot, and much more.
There are one of these compartments on each side. Plus an additional smaller one for night supplies like glasses case, contacts, and small items.
Water storage is under the front lip of the platform, and can hold up to 4 gallons with ease, but we only carry 2 gallons. In addition we can also fit 2 Yeti Hoppers, one on each side.
Cooking on the swing out with a 5lb propane tank mounted to swing out.
This was packing for 5 weeks on the road while moving from Missouri to Oregon. We had room for 2 Alu-box's on the roof rack with a Water-Port for our shower, and TRED's on the front.
