Ray, thank you for getting back to me on this shipping dimension issue I am having. Upon further testing of the UPS dimensions it turns out that if I set the weight of the item to 150 LB's while inputing in the correct shipping dimensions, the "correct" UPS calculation was rendered. However, If I removed the weight figure, or set the weight to 1 LB, it resulted in a shipping price that was 30% less. So, yes, it does look like that the UPS eCart object is factoring both calculations. However, if I set the weight of the product to the actual weight, which would be more like 75 LB's, the resulting shipping amount is "incorrect" because not enough shipping was calculated. To get the "correct" shipping amount requires a lot of playing around with the weights and dimensions.
