^Youre basically on track, but stuck on the payload thing. 3/4 ton/250/2500 class 2 model trucks have artificially low payload ratings. So that part, you’re not tracking on.
It’s confusing with all the people saying “you need a 1 ton”, but if you want actual verification, look at payload/gvws of new GM and Ford class 2 trucks. They’re offered with greater than 10klb gvws AND 10k gvw. But the truck is the same. This is not light duty vs heavy duty.
Also diesels with less payload rating is the same concept. Where Diesel engines load the front axle more, campers load the rear axle. Again, real world payload IN the truck bed is relatively unaffected by lighter or heavier engine.
That and I wouldn’t see a good case for helper springs and airbags. Pick one, not both.
It’s all good.
