I fully intended to release this alongside my retirement announcement, but due to the Workshop Uploader being a pedantic prick, I had to tweak a few things first.
Due to some naming changes in the def files it is suggested that you sell any trailers and remake/buy them. It’s not a necessity, but it is highly recommended.
1.5 includes HCT trailers. Woo. Please note there are no painted bumpers for the primary trailers at this point, but they will be added in a future update.
