I remember years ago the old International Scout was the only thing you could get with locking front and rear differentials.
They also produced a good torque when you got all four wheels spinning on ice that tended to make the whole vehicle spin, occasionally off the road and into the ditch, when people used them at higher speeds. Great for slow speed though. My mother just bought a Jeep Wrangler Rubicon that has front & rear push button locking differentials.
I became obsessed with getting an off-road vehicle last year & was seriously considering buying a '95-'97 Toyota Landcruiser, solid axles front & rear as well as optional locking front & rear diffs, built like a tank too BUT
horrible gas mileage & very small interior, so I decided I should
get 4x4 truck to haul & tow things too, almost bought a Tundra but
then the Titan
came out !! :idhit:
