One issue is safety, if your in some sort of accident there is no separation between cargo and driver in anything but a truck and most of your bungee cords and rope and whatnot are rated for a static load and not dynamic load so your likely to get knocked in the head.
Then there is always the one thing you want to carry thats too tall.
There really isn't much downside to a truck either, my v6 mini van could hit 25mog highway, the v8 4x4 truck 21mpg highway but loaded the both would drop down to 19-20. The truck is designed to haul a load where the minivan is designed to haul a couple extra people occasionally so maintenance cost is lower on the truck so overall cost is about even for a more capable vehicle.
