I never said your formula was wrong just that the simpler one you claimed was wrong, wasn’t wrong. The funny thing is they are in fact the same formula, as I pointed out in my other post. When talking about COG relative to camper jacks, it’s easier to use one set of jacks (front or rear) as the “datum line” so that half of the math goes away (d=0 for the moments at those jacks). That’s all the simple formula does and is consistent with what you learned.
I also don’t agree that percentage of weight on the jacks has nothing to do with COG. That’s exactly what it has to do with.
Interesting observation - I’ve not attempted that approach, but it seems there is more than one way to skin a cat - thx,
