Yes there is. You still need anti sway as well as trip wire for 3 way fridge and probably a charge connection for the van battery as they are usually thicker cables. All it does remove are the standard 7 pin plug connections. All vans I know of have 12 pin plugs along with anti sway and fridge fridge connections via anderson plugs.
