No more loaded down than usual. The GVWR on the Axis is 12,500 lbs and when I had it weighed ready for travel (with us in it) it came to 11,400 lbs.
It could be a perspective trick given that we're on a court and the front wheels are most likely closer to the camera than the back wheels and the Escape.
If I look at other images of our Axis (such as the one below) its sitting at the same height with or without a car on a dolly.
(That height is about 14" from the ground to the bottom of the hitch which has a 3" drop--had to measure to get the height right for the dolly. That pic was before we had a dolly and simply drove the car to the campground.)
The dolly only has a 50lb tongue weight when empty and hitching it up to the Axis causes no noticeable drop on the camper. Even when I drive the car up on the dolly there is no noticeable drop.
