Basically yes but not in the real world. You just quoted maximum numbers for both the truck and trailer. In reality you won't get to those maximum numbers unless you just try hard to bring your entire house with you.

You won't really known your combined weight until you load the truck and trailer down for travel and then go by a CAT Scale. That scale will show you your steer axle, drive axle, trailer axles, and your combined weight. As long as your combined weight is less than 25,300 your good for your GCWR.

What is really important is you CCC and truck axle ratings. You don't want to exceed those. Your pin weight effects all that.

It is easy to mix up GCWR and the various different actual weights. As long as the GCW of your truck, its contents, the trailer and its contents is less than GCWR you are good. For this calculation, pin weight can be considered as truck cargo or part of trailer weight. It is not double counted.

Asckreef notes, the most critical weight is usually what the 5th wheel pin adds to the truck weight. This should not take the truck over its GVWR including anything else that you are carrying in the truck. The rear axle capacity (should be on the white door label) is an important limit to keep an eye on.

Thanks for the info. The key is that I agree that I likely won't reach the max weight numbers so I will be under the GCWR.

I will find a scale to make sure.
