figured I was clear of a tree on a corner, spotter was waving me back, tree was between the truck and trailer, coildnt see it as it was a 4' stump that didnt clear the box height and pushed the back bumper up into the tailgate to the point where I could not get into the bed past my bakflip tonneau cover as I couldnt open the tailgate to unlock the cover. cooler full of rotten meat by the time I got to it 4 days later and a nasty smell following the truck after day 2 in 35degC weather. was an expensive $2600 weekend.
