Quite a project i can say - now 2 overland trucks further. From my experience these are long haul projects taking at least 1 - 2 years to complete on max throttle. Not everyone has the energy and time to pull this through.
To find the right vehicle - look around, ask around. In rare occasions a cheaper one its a good vehicle, but there are more searching like you do. Low millage is not always a guarantee for trouble free projects. I'd rather buy a used truck with a good service record than one with low millage which has done nothing most of the time. In the trucking world, a truck parked for years and years usually means trouble ahead when suddenly taking it on a 200K journey.
I can recommend to look for +100k/200K millage vehicles (pref. private ownership) - also ones already converted to an overland vehicle. Importing your own vehicle might just get you the one you want - the process is not so difficult, just takes a bit of reading,time and sometimes import tax.
The project can get far easier with a head-start (in time and money) like having a living unit with some equipment from a previous owner. As many already have found out the real costs comes with the conversion itself- to get a living unit equipped is a lengthy and expensive affair. Of-course it heavily depends on what you require, but here is where the real money goes when you try to get stuff right.
And last but not least - how do you think your journey will look like? An overland vehicle project takes many compromises - the perfect overland truck doesn't exist IMHO. In case you want off-road capabilities to the extreme, it generally means having to drive around 99% of the time on the road (with all the offroad stuff) when it comes to crossing large distances on overland journeys.
Good luck with finding your overland truck!
