I know 2 other people already answered your question, but since it's been quite a while since that update, more things have got in the way. Recently, I got sick (again), and school has been putting pressure on me really deeply. A few days ago my mother returned from the hospital since she had thyroid cancer and I can't go near her for a few days (and especially in her room) due to radiation. But not only that, the latest major update pushed my interest away from BeamNG deeply. Almost every mod broke and those mods broke my favorite vehicles. And knowing it'll be a long time before they actually get patched, even trying everything else (installing new mods, trying to make new compraptions, etc.) couldn't get my head back in the game. But it's not only that my favorite vehicle, T-Series, broke. My Anthem is currently built on top of the T-Series, which means I can't drive it around and test it properly. And my interest in BeamNG being taken away could mean this mod won't see the light of day. But if I get any motivation back with an insane amount of luck and don't forget how to mod, I might be able to work more on Christmas break and next year's summer. I know, this already sounds too long to wait, but many mods took literal months and some years to be released. This is also many of the reasons why I couldn't release my fix for the 2013-2016 NASCAR bodies. I've been working on other stuff and trying to keep myself happy, with the limited time I have every day. I got hired to make schemes for a racing game on Roblox and while it's been a blast making new schemes, it only took my interest more and also took away the precious time I have every day. Sure, we get to stay up 12 hours each day but you only start to realize it's still not enough time to do anything as many things take a few hours and time passes away very fastly. Even an hour or 2. But anyway... I'm sorry for the inconvenience and I still want to get back into modding and release this some-time. I hope you all understand and have a great day.
Fictional name ideas: Gavril Patriot, Gavril Triad, Gavril TR500 (or) 600, 700, 800 based on if you have configs that are better than base model.
Haulmaster sounds pretty cool honestly, but there ain't no way this is going to be a newer T-Series (a.k.a. the idea that has been re-used like 7 billion times now). It's confirmed it's going to be a Gavril now though.
