You wont make the blue or the red in that vehicle as those routes get rougher than what your truck can do and will likely lead to you having a real bad day (i.e. rescue)......
The green route is standard logging road (C branch), there may be a locked gate about 3/4 ways up in the clear cut at top.....sometimes its locked and sometimes not.

An interesting spot on the green route is an old hard rock gold mine......where the green line runs north and then almost does a 180 turn, come back from that to the junction that you dont have marked that heads northwest, then come back from that maybe 100-200m and there will be an old road that heads up to the right (basically between the green lines is a ravine if you zoom in) at the end of this road is a small tight landing (may be tight to turn that truck around at) over the edge of landing is a rope, climb down and look upstream to the entrance to Dead Horse Mine.

Havent been in it myself.....had my daughter with me when I got there and would be too difficult/dangerous for her to try, but have seen pictures.

Would that be Myles by any chance?? He was just over at my place and we were discussing the megasquirt setup with a marine intake for the 4.3. I have started researching it a bit and it may be a way to go....it's kinda crazy to build your own efi computer board and tune it yourself but from what I have read the instructions are great and the programming is very simple.
Like you say the price is pretty good cause you are doing the work yourself but would know it inside out after that
