I don't have a picture... but I will describe what I saw at noon today.
A early 2000 Suzuki Vitara towing a two axle landscape trailer filled with dirt with plywood tossed in to hold more.
All 4 tires were nearly flat from the weight and the poor Vitara was just bouncing going down the city highway at 25 or so... if the driver would have jammed the brakes the rig would have kept going...
I really think someone filled it by volume without regard to weight so much from front to back the trailer was bowed.
