mine looked like that---then i levelled the hitch so wasn't always pulling it uphill.
got about 2 more mpg!
but---couldn't leave well enuf alone, lowered the front till it was almost dragging and pickup actually got better mileage pulling the trailer than empty!
but it was way hard to unload---you had to kinda try to find a place where you could park headed way uphill---and going down the road, took forever to stop the darn thing.......
