What you described is called the SMB4x4, which is Sportsmobile's 4x4 conversion, as opposed to Quigley or any of the other 4x4 conversions. Point being if it lists "SMB4x4" then it will have all of that, or specifically list upgrades (Deavers and/or better shocks would be a good find).
A front locker is something you can add, which is to say you shouldn't pass up on a van that is lacking one... unlike the Diesel you want, a locker is an easy change. Also not to be confused with the lockouts or locking hubs which are also standard (although I'm not sure of the brand).
A front locker would most certainly be listed, locking hubs are implied by being a 4x4 and won't necessarily be...
Clear as mud now, eh?
