Thanks for that chart Digger. Was that a printout from your own individual scale setup?
Whoever's it was, we should have a Weigh-In party at their house!;D

I found a guy locally that owned a set of race scales. I made the chart in Excel in order to calculate the 3D position of the truck's CG.

A weigh-in party is a cool idea. How awesome would it be to have a database of various configurations and weights?

Not to mention BBQ, pizza, burgers, and plenty of whatever cold or hot drink floats your boat!
We had a "tire cutting" party one time and it was great fun. Definitely a good way to spend the day with family and friends.

I had borrowed a hot-knife for siping tire treads and about 40 or 50 or us, and about 20 Broncos showed up to spend a day in the driveway and court cutting, siping, chomping and sipping (and some guzzling too) and left a HUGE mess of rubber slices and chips in Jack's driveway.

Miss those get-togethers.
Ours was just fun and trying to get a little extra traction on the rocks and on the pavement though. A weigh-in would really have some informational significance for the future of our sport.

And it's just a darn good excuse...

Good to know about the passenger seat, fuel tank, & tires. And I did forget about the bulkhead under the half cab.
I'd bet each door weighs close to 100 lbs easy.
I never weighed the eB doors I built, but I did weigh one of the doors on my '93 with a scale I know to be accurate:

I'm curious about your technique to find the vertical position of the CG. Did you block-out the suspension?

Yes, blocked out the suspension and reweighed with the rear sitting on 12" risers I made for the scales and measured the shift in weight to the front.
