LumenRT vehicle dimensions aren't accurate

Semi trucks supplied with LumenRt are too large!

I measured the height to be over 17 feet. That's at least 3 feet taller than a typical semi truck.The 17 foot tall trucks in LumenRT tend to hit the bottom of bridges in our visualizations, which is unacceptable.

Here's a quote from the Federal Size Regulations for Commercial Motor Vehicles - FHWA:

There is no Federal vehicle height requirement for CMVs. Thus, States may set their own height restrictions.
Most height limits range from 13 feet, 6 inches (4.11 meters) to 14 feet (4.27 meters), with exceptions granted for lower clearance on particular roads.

The axle positions are also wrong with too much space between the rear axles.

Please determine the actual real-world dimensions for ALL vehicles and update the LumenRT Content.
