I drive my 37 on the interstate a lot. It has a 3.08 gear and a late model 250 so 65 to 70 is very easy for it. I have rebuilt the whole front steering including the gear box and it still drives like a 65 year old truck! Its not the trucks fault or the rebuilder (me), its just the nature of the beast. Most if not all of the problem is aerodynamics. Flat windshield, tall cab, lite weight... Windy days are really bad. I would much rather drive 45 to 55. To bad you can get run over doing that now!!
