For those who haven't worked around these, here are some other items to note:
Pic 1: You drive it looking out this window. Notice steering hoses outside door, steering wheel inside. That is the windshield while driving.
Pic 2: The raising line for the tube, and telescoping line for the upper tower section, are run from winches located obove the steer axles, below the fuel tank. Lines run under the hoist to tower end of the frame, inside the rails.
The 8 guyline, 1 raising, and 1 telescoping winches are hydraulic. The 5 yarding drums are chain/clutch driven.
They are: Slackline, Mainline, Haulback, Strawline, and Tagline.

"built using the same technology used by NASA to build space capsules!" Too funny! Seriously, though, their mobile loggers changed the industry, they were way ahead of their time. My friend, 90 years old, worked at Franklin River way back when, and he told me that the top producer at that division was a little SJ-4RT. Skagit produced some of the most unique machines ever used in the woods, they probably tried more new ideas than all the other manufacturers combined. Many of their machines may have not been the best, but they certainly got the ball rolling, encouraging others to develop new machines. Does anyone have the records on their production? I've often wondered how many 555's were sold in BC. It seems like there were at least ten TL-6's for each 555.
That was certainly one of the first in BC, if not THE first. However, Cypress was selling a GY built around American components in 1968, and grapples were used on steel spars even before that, so it's hard to say.
