The truck has a sticker that says cargo weight rating is 1772KG(3906lbs) “with this truck as manufactured”.
Okay, that is the truck's empty weight subtracted from the truck's GVWR.
It's all a matter of where you want to draw the line, and which numbers you choose to believe.
The RAWR of that truck is going to be somewhere around 10,000lbs or higher. Empty you're looking at 3500-4000 on the rear axle, leaving 6000-6500 for the camper, which resides 90-95% on the rear axle.
The weight you are currently at, even 1500lbs over the stated weight of the camper, you are not even stressing components. You could even live a little and bring that extra pair of socks.
It's just something you either have to be, or get comfortable with, or don't, and buy the F550.
