That all happened last winter, and I was fortunate to drive it around quite a bit this summer. Put ~2000 miles on it, mostly highway, but with a healthy amount of 4wd too!
Despite it's 235 engine being very crusty, it had no problems maintaining 60-70 mph on the interstate with 3.38 gears and 32" tires, except for long steep hills where it slows down to 35mph. Big tires and NAPCO running gear are great offroad, putting my freinds new tacoma to shame on big rocks/tank traps. That 7:1 1st gear of the SM420 is sooo nice!

I don't feel so bad about not having AC since the wind noise is about the same with windows up or down!

Average fuel economy ~14mpg on the highway, and somewhere below 10 offroad.

Installed shoulder belts for passenger & myself prior to departure... had to cut & weld mounting spot for shoulder harnesses: first photo
