I’m all of 167 pounds above you. My Laramie had a payload of nearly 1700. I knew the Longhorn would be lower, but I didn’t fully comprehend how much lower.
I didn’t get the MFT or Rambox, but I did get the off-road group. That, the sunroof, and the 33 gallon tank are what hurt my payload the most.
Most of the time, it won’t be an issue. But on road trips when I’m taking the rooftop tent, a powered cooler we just bought, our “stuff”, a Front Runner rack, and a Retrax cover, we might be pushing it.
I considered a Power Wagon, but similarly equipped, it actually has a payload about 100 pounds lower (a regular 2500 would be much higher, no doubt.)
I’ve got no right to complain, of course. We’ve got luxury cars with a cargo box out back. Incredible machines, which we’ve loaded up with goodies and that doesn’t come without compromises.
