First up, "Hungary Map" ( http://ets2downloads.com/maps/hungary-map ) this is totally separate from the main game map. It requires a new profile to enable it to be used, and has a slightly different way of activating the mod vs other ones. It's not totally perfect, i.e the odd invisible wall in places where you wouldn't expect it but they can be driven around. Totally different feel compared to the UK / Europe map provided with the game, and also the mileage is more realistic, i.e it will take you a few minutes to complete one mile vs one minute per mile. Okay, it might not be one minute per mile in the game but those familiar with it will know what I mean.
Next, World of Trucks ( https://www.worldoftrucks.com ), whilst not a resource as such it's a handy place other than Steam for uploading screenshots to & making a custom number plate if you so wish. My profile - https://www.worldoftrucks.com/en/online ... p?id=15584
For some general "mods" http://www.modsaholic.com/forums/index. ... simulator/ a useful site with lots of items - of course all mods are installed at your own risk!
Finally a Youtube account that covers all things "Sim" DaSquirrelsNuts ( https://www.youtube.com/channel/UCSeb5K ... 0WwEjUzM_A ) "Squirrel" also has a 'Twitch' livestream usually on the weekend where he'll stream games and these are usually advertised on the Youtube channel.
Hopefully these will be useful to some, and if you've got any more to share then it's always appreciated.
