Nice bus. Ideas: Make the bus have tow hitch. Make articulated bus, bi-articulated bus and tri-articulated bus, but with tow hitch.
Looks like you litteraly just added a tow hitch and all those configs. You can post the configuration file, noone will stop you Also, thank you for liking it!
Take tow hitch from some other vehicle, re-position it in blender, add two nodes like towhitch jbeam has them that will be ball of the tow hitch and it's base, then add beams between bus frame and tow hitch similar way as those are in some official vehicle. It is not very complicated as even I could make it, but you might need to make it bit longer in Blender, like I did with semi tow hitch (haven't released it). For bus frame you need new slot for tow hitch too, I made new frame for semi to make that. I'm not sure if zip works in mod folder at all, haven't tested that, but at least you can see how I made it for semi, maybe it helps you make one for the bus.
It would be far more easier for me to make addon towhitch for the bus I'm afraid, but not sure when I have time for such. Perhaps mod author can use file and information I attached to make tow hitch as buses usually do have a tow hitch? Or someone who has time?
To be honest I really damn hate the bus sounds that this has been given as it sounds nothing like what the actual real life counterpart would. /rant
You need to edit jbeam files with Notepad++ and also use Blender, do you know how to do that? If not, then you might need to learn Blender with some tutorial first and look tutorials index from content creation section if there would be something useful, also Wiki is good source of information, read parts about nodes and beams.
