There are a number of sets of Lego 42035 here. There are 7 mining truck and 7 bulldozer truck instructions implying that originally there would have been 7 sets here. This hasn’t been checked to be complete so I have taken a photo. If you count up the wheels I can see it wouldn’t make 7 sets so please do not buy assuming that it would build 7 full sets. Happy to post.
