The axle manufacturers load capacities are not the official load capacity once they are fitted to an RV trailer.
Because the trailer manufacturer has the authority to set them to a GAWR.
The installed axle (s) may match-up with the trailer manufacturer's specs as built or reset to a lower value known as Gross Axle Weight Rating (GAWR).
The GAWR is the official
value the trailer manufacturer uses to build the trailer around and is the value for tire and rim fitments.
Here is an example of a certification label with a GAWR set at 6750# for 7000# axles.
For all RV trailers the label above must be permanently attached to the LH forward external section of the trailer.
