Really nice pickup to be hauling firewood in! Of course back when they were somewhat new it wasn't such a big deal because you could just go buy another one.
I had 2x2 stakes and cab-high 1x8 sides and front on my "old" K/20. The stakes were about 8-12" taller than the sideboards. One time a bunch of us young folks went up on a powerline ROW in Alaska to glean firewood for the church. It was cut in odd lengths and stacked to the side just free for the taking, IF you could get in and out of there. It wasn't any more than a dozer trail, and of course all the easy stuff was gone.
With all that young manpower (and young womanpower!) we loaded my pickup up to cab high with 8-10' birch logs, and then slung a bunch of 12-14' poles up on top sticking out over the cab. Another guy brought a LR-90 with a little 2 wheel open cargo trailer. Coming out there was a really steep muddy hill. My loaded truck went right up but the Rover and the trailer didn't make it 1/4 of the way. I only had about 20' of cable so I had to back about halfway down the hill to hook up. The big mean green Chevy pulled that Rover and its pathetic little trailer load of wood up that steep muddy hill without even groaning
