OK so am going thru the new to me 5ver since being used you don't really know,Its my 1st trailer of any size anyways and the first with brakes, My sprinter has two axles and while I was packing bearin...
I would set them up and pull onto a grave area, while moving forward step on the brakes or push the lever and see what the 4 corners are doing. If the prior owner had less weight on the front than the rear the front ties might have been sliding while the rears were providing the braking. Any difference in the wear on the front tires over the rear?
