Is the same model with crawlers but i change the crawler for wheels and change the rear fenders.
I add trailers to the rear attacher. By default only have rear attacher for trailerlow.
You can post this mod in other sites and change, but please respect my work.
If you want create another version or fix this version do not launch what v0.1, v0.1 is this, your modification is v0.2 or v1 or something else.
