Any load carrying vehicle should be happy with any load that you can fit in the space, because the designers know that someone will be pushing the limits.

There was a recent kerfuffle involving a new Ram truck. It was a crew cab 4x4 3500 dually, IIRC. He picked the model because it has a load rating of 7500-ish pounds. He owner installed a slide-in camper that weighed 6500lb fully loaded, then took it on a 25,000 road trip through mountains and "unimproved" roads in Mexico, where the truck frame snapped between the bed and cab. The guy insisted MFR defect. It turned out that the defect was the nut behind the wheel. The load rating he calculated was for the standard cab longbed 2wd. The correct rating for his truck was 5500ish, and 2/3 of the camper's weight was over or behind the rear axle, making it a giant counterweight.
The fact that it lasted as long as it did is either a miracle or a testament to the engineering, depending upon how you roll.
