Brakes and boat ramps

[Kinnick]

My understanding is when you put your vehicle in park and apply the parking brake, it only locks the rear wheels. So if you are on a wet slimy boat ramp, it is possible the rear tires could slip and your rig could go in the water. That is why they say to put it in 4wd so it links both axles, therefore when you put it in park and apply the parking brake you essentially have all wheels locked. Am I correct that even though I have a V8 that has full time 4wd, I would still need to put in in 4 high to essentially put it in park and have all 4 wheels locked?

Lock the center diff

The parking brake would only keep the weight of the truck and boat from resting on the Parking gear/pawl and allow you to shift easier. But you are correct in that 4H would connect front and rear wheels together for more grip.

That said, there arent too many boat ramps that require 4wd to launch a boat. I used to use a fwd minivan.

If you are dunking the rear axle in the water you should do the axle vent relocation mod to prevent water incursion.

there is no 4hi switch on a v8, its always in 4hi.
