Heres a sketch up model of the bumper i started last weekend.
I used 2-1/2" Square tube and 1-1/2 X 3" tubing and mounted it to the rear crossmember on my Runner, I couldn't go directly to the frame it would interfere with the 63" chevys. I can take a real picture next time I get to go home.
I haven't been up there in a couple years, I was thinking about going camping up there next summer. Does anyone know if there are any fish in those lakes?
