Its a coachman clipper. Supposedly light weight . I have no idea why these builders spec the axles out to maximum dry empty weight.They did not allow much of a safety factor. I never overload my trailer and run dry. It came with a 3500 lb axle.. I replaced it with same because I could not find any bigger with the dimensions existing.I compared the two side by side and whoa.. what a difference in camber.I suspect I bent the axle when I had a blow-out and the trailer dropped on the rim.I am thinking a stiffer spring or I may design an air bag configuration/modification.Appreciate thoughts/ideas
