2 versions: 2 axle and 3 axle * 2 axle: 4WD with differential in middle * 3 axle: front and middle axles are connected with differential in middle, third axle is not connected to engine * cabins, front and rear axles are same, only difference is the third axle
both trucks support: - HOG steering - full suspension on all axles including the third axle (live axle suspension) - opening doors - tilting cabin, can be locked to prevent mis-opening - fifth wheel (lock from 42078) - fake V8 engine - lockable front grill - ground clearance is not much, 1 stud at most
3 axle version supports "raisable third axle", it raises 1 stud only
has not built 3 axle version but I partially assembled and saw it works.
problems: - front suspension is a joke, it only causes truck to tilt left or right due to heavy cabin - there are a few illegal connections (windshield connector, door connecting 3x7 panels and interior 3x11 black panel) but other than that runs very well - when cabin is tilted, the truck seems like about to roll over due to weight of cabin but there is a stopper built and it prevents that to happen
LXF and stud.io: they are same truck, stud.io fixes the illegal connections and has nice render, other than that it is same with LXF.
