I once converted a 3/4 ton Ford van to be a "Mobile Command Post/Base Camp".

It was this concept that led me to customize it the way I needed it to be to fit my need.

That had me arrange bench seats to double as beds, w/storage boxes underneath each.

I carried food, water, & a porta-potty at all times. My camping supplies were all in the van, at all times.

Space was allotted for weapons storage.

Communications consisted of a CB and AM/FM receiver (pre-cell phone era).

Space was reserved in the back for modules. (kitchen, general cargo storage, work bench/tool storage). I put in what I expected to need per trip.

The concept is what gave me the direction I needed to achieve my goal.
