The number on the brochure is not what you can actually pack. Enter your rig’s ratings and what you carry, and see the cargo margin you really have.
The truly accurate way is a CAT scale, loaded the way you actually camp. Dealer-installed options also eat into the sticker numbers.
How it works: cargo capacity = GVWR minus dry weight, water at 8.34 lbs per gallon, propane, and passengers. Under 500 lbs of margin is where tools, hoses, chairs, and food quietly push rigs overweight.
