it's very far from done, i'm having a lot of trouble with the lights and glass. but for anyone who wants to try a very big pigeon based on a t-series (or a t-series with just 3 wheels) here it is.
Would be cool if you made a version with normal T-series cab and bodywork except for a fenderless hood. Even cooler if it also has fifth wheel and upfit options from the normal t-series
