I have decided to replace the silver aluminium front bumper on the skip truck with another aluminium one, that I got from Rigid RC it is similar to the tamiya original one, the reason is to protect the steering servo on rough ground and grass, I also blanked out the lower light inboard of the outer ones
old bumper
new bumper
the Mercedes 4* 2 tractor has an aluminium bumper fitted to but is slightly different as I got it from another supplier
I also decided to replace the rear cab support with a metal one again from Rigid RC
