2006 Nissan Frontier Crew Cab SE 4dr Crew Cab SB (4.0L 6cyl 6M)
Superb truck +1
 This truck has been wonderful.  There is plenty of room for our sons in the back seat even on 200+ mile trips to see family.  The is superb power and even pulls the 6500 lb towing without a problem but make sure you have trailer brakes if going very far.  This is by no means a "compact" truck with the ample room over the previous Frontiers.  I am running Mobil 1 synthetic and Nissan says,even though they recommend standard crude in the owners manual, that this is okay for warranty.  I work at Nissan with guys that oversee engine testing they say these 4.0 are just about bullet proof.
