After a lot of consideration, research and headache, I deducted that, at least for what I intend to do, van would be more suitable than a pickup.
Ford transit custom can tow 2.5t which is enough to tow a 2 cow trailer, Has much more usable space inside, takes a lot less fuel!
But... That's only if you don't plan to use it off road, I.e. live just of tarmac road.
