I’m not sure how any advice on here can be that relevant as you say that you operate abroad (but not where), and do not need an O Licence (lucky you!)
Generally european spec trucks have different model numbers and axle weights to UK ones, and as you are looking at used I would just “Google” used trucks in your area/country, then pop down and have a look as you have a pretty good idea of what you are after judging by the pictures posted.
Not a dig, just an opinion.
