A few on here have said the suspension is crap on stock Rangers. Probably ok on sealed roads. But not for what most of us like to do. Bit surprised there wasn't some sort of torque converter lock up in low range to improve the ability to control road speed going down hill though. Maybe there is something in the vehicle handbook.
In fairness I haven’t seen the owners manual so there might be a setting to give some torque lockup but also being only 2L there is probably not a lot of resistance considering the vehicle weight
