Payload sacrifice going from regular cab to crew cab

In general, how much payload capacity do you sacrifice going from regular cab to crew cab? Let's keep it simple and compare single wheel pickups-not duellys. I did the calculation for the 2013 Chevy Silverado 3500 and it was 581 pounds! Is that normal?

Welcome to the forum!
Word of caution, you may want to read a few of the numerous threads on this exact topic. And dont be offended when this thread goes off the rails about payloads and gvw, because they always do.
In general, your analysis above is correct. And the ultra conservative approach to payload is to use the mfgs payload reccomendation. Or if you're a bit more educated on the subject, you will be able to determine what is a comfortable load for you that is within the real world capabilities of the truck.

Pickup trucks are just amazing. You start with heavy duty construction, then add a crew cab, then get a diesel to pull it, now the thing weighs so much the cargo capacity drops to a fraction of the weight of the truck.

Your going to use the truck to carry a TC in the bed which the trucks rear axle takes most if not all the load. Both trucks have the same 7050 RAWR that will carry the TC weight.
That 581 lbs is probably a gvwr based payload difference. Using the trucks 7050 RAWR between a std cab gas engine 4wd vs a crew cab gas engine 4wd shows around 250 lb difference. I would 'spect the Dmax/A would have about the same differences.

Some of the newer gen 350/3500 SRW trucks with those high 11500/12300 GVWR with 4000-4500 lb payload stickers will and have overloaded the truck 7000-7050 lb RAWR when its all used in the bed. Watch those TC numbers your settin' on the trucks rear axle.

Taking your 581 lb, I would estimate 1/3 will go to the rear, so you have to get camper about 200 lb lighter.

I was talking about taxable payload but since you mention rear axle carrying capacity do you mind sharing your thoughts on how a crew cab compromises that as well as taxable payload?

You are talking taxable payload, or rear axle carrying capacity?
2 quite different directions.

Sounds about right.
