.I haven't gotten as far as planning for 'on board storage for trips' in re my rig yet, it's still in the sea trials and fitting out stage. However, I do plan to use vintage storage options to go hand-in-hand with my vintage rig - military storage containers, canvas, metal and wood. However, I am getting ready to refurbish an old military storage trunk that will house roadside repair items, recovery items, extra oil and so on. It is even big enough to hold a small, 3-ton floor jack. I used this thing for this purpose before the rebuild; it has so much storage it was never filled. It's the weird green box in the pic.
Here in the next couple of days I'll be receiving 4, vintage Polish military bread bags that will attach to the galvanized capping the seat backs are against (or get tossed into that box). The hold just about anything for storage. Those are the types of things I'm planning on using.

Someday, @Correus, I'm going to find, or make, some units like this in various sizes for the hell of it; just to try as a fun challenge and to see how well they work on an adventure.
One as a desk unit like this; another sized to fit available space in both trailer or van. I like how it's all self-contained and used the lid as desk top.
