Worked on this a little this week..
Adding a couple small details like mirrors, these are slightly different than the ones I used on the dump truck.. I think I'll paint them white cause crome cost to much..

Again nothing fancy but I think they will look pretty good.

When I get better at working with brass I might get a little more detail in them but for now.

Like the dump truck a simple steering wheel

One of the down sides to doing these at 1/16 is the 1/14 stuff is to big and the 1/24 is do small... there just isn't a lot in this scale for detail pieces so you kind of have to "roll your own"

Again wiring is pretty straight forward, a master on/off with a charging jack
Terminal block for the power and lights...I'll stick it down somewhere
I always slip a little cut off piece on the diodes so after I cut them I still can tell +/-

Wiring in the headlights, Yes this one will be blue... The way this grill and headlight lens go in you need to paint the cab before you put it together...

The head light lens are the "button" that holds the grill in so once you wire in the lights your stuck.
