Someone feel free to correct me if I'm wrong, but I would be cautious of any "hitch weight" spec on a manufacturer's website. My understanding is that most of those #s are dry (unloaded) hitch weights. I spent what felt like forever this past fall looking at floorplan after floorplan, including toyhaulers, and we finally decided on a Grand Design 31MB (midbunk, not a toyhauler). Ultimately decided that based on our needs, a long bed made more sense (of course that ruled out a Tremor

).
Just for information sake, here's my numbers... (2021 F350 6.7 long bed)
