This is from Ford's Product FAQ -that's nice to know. fwiw, the 2020 ford raptor has a GVWR of between 6650 and 7000#.
i think ford's is not limited by the GVWR.
(you might be restricted where you can legally drive)
Why do certain models prohibit some accessories?
We have a Bronco for every customer. Many Bronco accessory items can be added during or after vehicle delivery at the dealer. We engineered Bronco for maximum off-road capability and GVWR restrictions may limit combinations of certain accessories.
