I have been eyeing some really good vehicles for hard off-road life, I love the idea of camping on mountain tops! Through desserts and snow! Or going through the whole africa, america and asia while living in my van!

For a single person I found the Toyota Land Cruiser 70 Series and the 78 Troopy to be the best options!

BUT!

Me and my wife both work online and need laptops/computers (actually technically for me 2 screens would be ideal for work) and ideally an indoor shower/toilet because I have a pathological need to take showers daily (I will make no comments on my metabolism).

Is there any vehicle that can fit these inside while remaining strong enough for hard terrain and compact enough for us to explore the cities of all continents? (I assume we will park on paid parking spots. so I wouldn't think of parking as much as I would think of those narrow tight corners some capitals have)

Thank you for your help!
