A lot of ppl have tried & some even made cargo boxes to solve the issue. Problem is there's more to it than yanking the seats & dropping in the boxes. Those inside trim panels are also different & need to be swapped out & that ends up being very costly.
The pursuit spec'd versions come in the 5 seat config, but typically you cannot order one unless you have a contact at a dealership.
It was possible to order the 3rd row delete version in a base Durango, but it could not be ordered with the tow pkg

, the 2rd row bench became mandatory & as I recall was limited to the cheaper black leather material. For '26 the Hellcat versions come std with the 5 seat config & you can get the Laguna leather (in the Jailbreak ver.).
Not a lot were ordered 3rd row delete, so they are very hard to find used.
