We just got our 2006 Cardinal fifth wheel back from a very reputable garage. The axles had been set a half inch off side to side and welded in place at the factory. One tire wore badly but it took awhile (very good tires) and was otherwise barely noticeable. But when we had it checked sure enough the axles were off, and we had to have new axles, this is a 2006 fifth wheel, we are very disappointed and out almost twelve hundred dollars. We are very diligent about the maintenance of this trailer, and only drive to Montana from Phoenix and back most years.
