My dad was a fireman for 54 years. He said the fire fighters may get all the glory, but it is the fire preventers that avoid the need for fire fighters and typically go unnoticed for it. He told me to be a fire preventer.

Thanks all.
I am a helicopter mechanic by trade. So everything I do is preventive maintenance Unless a pilot **** something up haha.

That is wrong Never discharge the system doing that
there is better ways to do that, without shorting it out.
plug in a cell adapter to the 12volt socket or cycle the key a few times...

That is a matter of opinion.
If both cables are disconnected, what you are saying to do is doing nothing different than what I recommended.
its adding a load rather then shorting it to ground.... short circuit is different then adding a load to remove charge from the system
Even a resistor load will reset the computer
it only takes a few seconds to reset the computer on one these anyway.... by flipping on the headlights... with the battery disconnected why risk damaging a ECM or something else that will cost a ton of money to replace just to save a couple of seconds?

Perfect. With all the resistance that exists in the grounding system, as you have pointed out numerous times, there should be enough load so there is. It a direct short like you say.
that is still a Resistive load
it's still not a short circuit
and since it's an incomplete circuit it would have no effect..
i.e turning the headlight is a completed circuit which can discharge the system without potentially causing damage..
a good example is the air bag controller module it uses a Resistive load (a bleeder resistor)to safely discharge the module.

Brent go away, go measure your wheel height again since you seem to be confused about what 2" is
Jason, the 02 sensor's on these trucks are rated for 100k miles, I would recommend changing all 4 at once, you can get a good price from rock auto, the set of 4 ran me about $200 or close to it. you may want to also order a crows foot & 02 sensor socket to get the drivers side one in & out it's a real *****, you wont hurt anything disconnecting the battery, while you have the cables off give the battery post and cable ends a good scrub with a wire brush. These trucks are pretty finicky when there is power fluctuations, poor ground etc we see it all the time.

i looked at my parking spot it was just a bump in the spot were i park so the axle was tilting forgot it was a solid axle... it's still stupid to short the connections out anyways This is not a vehicle from 1960s where you can disconnect random shit when it's running without damaging anything and short shit out without problem... mine resets as soon as you pull the power cable from the battery anyways, so the NNBS don't need to be discharged at all..
it WOULD in fact cause damage if reverse polarity protection diode(s) were bad(or none were in place)
