This is going to be a "working" stovebolt because I plan to be hauling 2-ton of coal with her to heat my home in the winter and since I will have to cross over mountains she has to pull up some steep grades.

So are you guys saying when I'm driving I can shift LO-HI on the fly? If your doing a haul like what I described would you go 1L-2L-3L-4L---then shift 1H-2H-3H-4H OR 1L/1H-2L/2H-3L/3H-4L/4H??
