My comments were in response to the OPs original post where he wrote:
"Shaving weight...often times in extremes was everything for the track. I don't think overlanding (or...pick whatever word you want) should be any different."
I get where hes coming from but I don't necessarily agree with the statement because of the extreme.
The OPs comment reminded me of most of my peer group who is into racing, track cars, and the Lemons race series... the level in which they look at weight reduction and the amount of obsession over it gets a bit too much at times.
Don't get me wrong, I know all this stuff matters, and I agree about the cumulative effect of weight, but I just don't take to to an extreme. I am generally more mindful of where I put the weight, trying to avoid areas that increase CG.
An easy example is many people here are most likely to get a 285 over a 255, that alone as a starting point should be obvious to anyone in the know but many just like the look of a fatter tire. I also agree with what you say about intelligent decisions, but often times its a money and availability conversation.
I've driven many different rigs, even ones that are very loaded up, and the best handling ones were not the lightest trucks, it was the one with even better suspension. Specifically long travel setups with a secondary bypass.
The weight appears to be less of an issue when you can actually control it.
