Payload & GVWR

You can get different sizes with different GVWR's, which will effect payload.


Payload = Trailer GVWR - Trailer Weight

Your trailer's GVWR is the amount of weight that the axles can carry, to determine payload all you have to do is subtract how much the trailer weighs.

We have a more compressive explanation here.


The longer or bigger the trailer, the heavier it is. If two trailers have the same GVWR, the smaller trailer will have a higher payload, because it's not carrying the extra weight frame weight.


The payloads listed below are for a standard Lamar Trailers, adding additional options will change capacity.
