It has about 900# cargo capacity which in reality is only 600# to keep the axles within specs. Maybe thats why they smartened up and the new 2608ws has 3500# axles now. We have to load everything ahead of the axles yet all the main storage is at the very back of the trailer.
Very deceptive number juggling imho.
This is not unique to Forest River, pretty much all RV manufacturers do it.

Agreed, all manufacturers do it.

The following is a verbatim quote from a NHTSA Q&A document.

The FMVSS have requirements for the manufacturer to use proper tires and rims for the gross axle weight rating (GAWR). The manufacturer may determine the GVWR by adding cargo capacity (if any) to the curb weight of the vehicle as manufactured. The wise consumer, before purchase, will determine if the vehicle has sufficient cargo capacity to carry the weight of water, additional equipment (such as televisions, and microwave ovens), and luggage. The manufacturer’s certification label must show the GVWR. The GVWR must not be exceeded by overloading the vehicle. There is little the government can do to assist a consumer who has purchased a vehicle that has insufficient cargo capacity for its intended use.

I have to chime in on this one.

I believe there is a marketing ploy on the part of the Rockwood/Flagstaff folks to provide the bare minimum axle rating so as to keep the GVWR as low as they can, This is to support the idea that the units are 1/2 ton towable, or in the case of smaller units they can be towed with small SUV's.

Other manufacturers such as Northwind Manufacturing (Artic Fox and Nash) offer substantial Cargo Carrying Capacity in their units, at the risk of being labeled "heavy units". They are only heavy if loaded to max CCC, which would rarely be the case.

As for me, I upgraded to 5200# axles 4 years ago and have never looked back.

No I don't carry more stuff in my trailer now, I just have a reasonable margin of safety when it comes to the running gear.

My 2 cents

Changing to axles with heavier load capacities may make an owner feel more confident but it will not change anything else. Only the vehicle manufacturer or a certified vehicle modifier have the authority to change a vehicle's GVWR or GAWRs. So, your trailer's certification label still displays the correct values because the GAWR values as set by the vehicle manufacturer remain the same unless modified and re-certified.

Read what I said, "No I don't carry more stuff in my trailer now, I just have a reasonable margin of safety when it comes to the running gear."

The upgrade substantially reduces the probability of a failure on the highway, because the load bearing components are now running at 60% of their capacity vs 95% capacity as delivered from the manufacturer.

Yes the upgrade makes me feel more confident, with sound technical reasons for the confidence.

If the manufacturer had installed 5200# axles and appropriate tires and wheels, he could hardly have sold the trailer as 1/2 ton towable, that's my point.

Airdale has told you how they set the GVWR, but again not how the proper axle rating is determined.The axles do not need to to equal the GVWR as they do not carry all of the weight period. It's not a game being played with your safety it's really simple math and physics.
