Here's a link to the 2006 Journey Brochure.

In the specifications section it lists the heights as 11' 6" to 11' 8" depending on model. There is a catch however. On the last page there is a disclaimer stating:
The height of each model is measured to the tallest
STANDARD feature and is based on the curb weight of the typically equipped unit. The actual height of your vehicle may vary by several inches depending on chassis or equipment variations.
The key words in this disclaimer are "
tallest STANDARD feature". That means even if the unit was purchased with the OPTIONAL factory installed satellite dome or other optional equipment mounted to the roof it is not included in the stated height.
