Frame and 11k lb axle are the same on the DRW and SRW. The difference is the tire, rim and suspension ratings. The weakest component in the system gives you the OEM rating.
I suggest getting an actual rear axle weight of your truck and subtract your tire ratings to get available pin weight capacity. Figure 20% of the FW's GVWR will be the realistic pin weight. If you are considering a toy hauler, the pin weight will be closer to 25% of GVWR.
If these figures don't give the numbers you need for the FW's you like, you need a bigger truck or need to upgrade components of your current truck. WA only cares that you register sufficient GVWR for your truck to compensate for road wear, each axle is under 20k lbs and you can stop in set distance with your current load. The rest of the ratings on the truck are enforced only for warranty. We can discuss what components to upgrade later based on your findings and how you will proceed.
