i have a 2008 sierra and planning to put a sub in. and i was just wondering where people pull the wire through firewall?

On the drivers side, there is a large rubber grommet where a bunch of wires go through. You can easily poke a hole through the rubber grommet and run your wire. Best way to see it is from the engine bay. Hope this helps.

  The use of absolutes like "always" to describe gear selection, and giving free advice at a boat ramp sounds like a recipe for disaster. It's a boat ramp, not a farm, for starters. IMO gear selection should depend on the obstacle. If low range is working and this is a slower speed, controlled ordeal, I'd keep using that.

  I had a boat for many years, never had a problem even with a 2 wheel drive 93 Silvy for 20 years. Good tires, proper use of the gas pedal worked.

  I read through that and I won't lie, my eyes rolled at some of the quirks about how it can turn off the trailer braking for example but I can see how it could help control or even up the torque applied to the ground with each wheel in a boat ramp scenario. But of course what it can't do is increase the torque to the wheels if the need is there as it ends up being like driving the four wheel drive version of a two wheel drive ( high range that is ). So far the neighbor that ended up with the 3.0 duramax with the max tow package which meant the 3.73 gears and high range only, I think its been doing ok for what he has been towing but doubt he ventures off into the soft stuff with his holiday trailer. He may have towed his dads river boat locally with it ( he always used his 6.6 duramax before ), I'll have to ask him sometime if he got into a lack of power to the wheels situation as after all that engine produces a lot of torque at low speed once the turbo winds out a bit and I think it has the 10 speed and if so they have a pretty good first gear ratio at 4.70 I see which is vastly better than the 3 or four speed overdrive models of years ago.

  I did shorter OCI"s for many years without an issue, fights sludge and wear IMO. Recently started using Amsoil, will not do the recommended/advertised miles between changes.
