I have
First at street speeds (under 40 mph) and then going down the highway in 4 High I turned on the CDL to see what the effect would be. Truth be told, I couldn't tell the difference in straights and curves. At slower speeds when I take sharper turns there is remarkable understeer (takes a wider turn). Also there is some wheel hop but only on dry surface.
I love the idea of PT conversion, especially since I am hoping to get underdrive gears in the transfer case anyway, but I find myself driving in nasty, slippery wintery conditions about 4 months a year and I think for that an unlocked 4H is ideal.
Someone please correct me if I am wrong.
I agree with your logic on slippery condition driving. We live in northwest Montana and see a lot of different types of wintry conditions and test drive the cruiser in all of them. I think the only time I ever push in my CDL is when the snow is approaching the frame rails and is powder. When it comes to any other condition, icy,packed snow, etc. having the CDL unlocked and the stability control working, it has been great.
