UNDERSTAND IT! You must keep all wheels rolling to keep steering
control, and headed down hill.

It matters alot. The recovery of sliding is not the application of more
brakes, it is the application of more gas. If you are rolling along using
the brakes as the sole means of controlling speed, then you are asking for
trouble. The best way to control speed is to use the correct gear, and
gentle applications of the brakes and gas, depending upon what is happening
and the surface you are driving on.

If you rely upon the brakes alone to regulate your speed, then the vehicle
can quickly attain an uncontrollable attitude that can result in excess
speed, and severe angles of slope.

TJim said that LO range, 1st gear is best, but this is not always true.
Sometimes LO and 2nd is better. It really depends on many factors. His point
is that the best thing is the drive train should be taking the load, not the
braking system.

Yup, my Dad told of many modifications he did, like add another
transmission, bolt washers to the top of the piston to increase
compression. They were limited by only their imagination, a very
different world from all the regulations we have to put up with.

He is talking about control. 'Never' go down a hill in neutral or with
the clutch in!

If you rely on the brakes, you lose steering way to fast or the rear
tires lock and slide out and you tend to nose dive because 60% plus the
down angle means more like 80% of the braking resistance is on the front
tires.

Also the springs aren't torque loaded, this makes the vehicle 'float'
down the hill with loose springs. The body floats on the axles instead
of being sucked down to them under torque. A perfect combo for a 45 deg
slide and maybe flip.

I do disagree with 1st low though.

I climb sand pit walls and go back down them and 1st is too low, all 4
tires start skidding. I use 2nd low mostly, sometimes 3rd and some
gentle taps on the brake while still in gear. Staying in gear prevents
the front or rear tires from locking up when gentle braking or you would
stall the engine.
