No.
Trailer cargo capacity is measured as dispersed weight as is the ramp. This means that if you trailer is rated to carry 10,000 lbs. of cargo, that does not been that it can hold 10,000 in a small area.
Example: You have a forklift that weights 10,000 lbs. and your trailer is rated to carry 10,000 pounds. Because the weight of the forklift is confined to a small area, the ramp may not be able to hold your forklift.
Make sure that your dealer knows what you intend to carry and its weight, and that these requirements are listed on your order.
