Your truck has seating for six, so do you expect it to meet all other specs with six 200lb people riding in it?
Manufacturer gives you maximum values and it's up to you to choose how to configure your truck and choose a trailer within its limits.
You put options on your truck that ate up the payload. SRW can have nearly 5,000lb payload with the right set of options. The options you have reduce payload but don't reduce trailer towing capacity so there is no reason for them to dumb-down the buying process so people no longer need to think.
