Here's a super sweet Delica in NZ:
FWIW I think Delicas are freakin' cool. But I also think they (and other minivan platforms) are a bit small. The video kind of shows it.
And I have personal experience too. I started to convert a 2003 Astro AWD: 4" lift, wheels, tires, platform bed with storage underneath.
My next step was going to be a complete 5.7 V8 4x4 drivetrain out of a '98 Suburban. It's close to a bolt-in conversion.
The thing is, even as a single, travel light, less is more kind of guy with no kids or pets, the Astro gets cramped. When my girlfriend is with me it gets even more so.
So I recently picked up a low-mile 7.3 RB. That's a story for a whole nother post, but just my 2 cents' worth, it's a lot more realistic for an overland rig...
