And what angle are the spindle arms with respect to the axle tube (i.e. are the spindles above or below the axle tube)? According to the diagram, the spindle arm of the 22down axle should be no higher than horizontal under full load. Unless you loaded it to the gills when you picked it up, you should have been no where near to the fully loaded (on the wheels) weight of 7000 lbs. Notice how the GVWR of your trailer (7714) minus the 714 tongue weight magically matches the sum of the rated load capacity of the axles? That's no accident, its how its calculated.
It would take quite a nose-high, virtually unmanageable, tow to put so much weight on the rear tires to deflect them into the metalwork - the Dexter documentation I referenced said there should be 3 inches of extra bump clearance under static full-load conditions. That doesn't look even close to 3" in the first picture and I bet you were unhitched. Were those pictures taken with the trailer approximately level on level ground?
That 'copper' piece is called the stop can (not copper - that's just the plating) and is what stops the gear train from pulling the slide actuator too far back into the frame. It stalls the gear train and makes that ratcheting noise like the variable torque clutch on your cordless drill that tells you that you really should let go of the retract switch now. It shouldn't slide across the tread either. The only way I can think of that the stop can could drag across the tire when opening a slide is if the trailer is level while parked on an extreme grade. Of course the other way is that the slide actuator shouldn't have been located at that place in the frame in the first place.
