They did put autolocking hubs on the 205 when they came out with them in the early 80's (on one tons) and what did the sales brochures say in 73-75 about fulltime 4x4 advantages? There are pros and cons to both. I find the idea of a Awd truck with a locking center differential interesting .These trucks are out there after 30 plus years so they cant be that bad . i think GM should have offered fulltime as an option in the autos instead of making it standard because it didn't make sense for most street driven vehicles.I love my part time 4x4's and my fulltime 4x4 . Yes fulltime is an old technology along with straight axles , carburetors ,3 speed automatics and small block Chevy's but I personally would rather have a 73-87 chevy over anything that is being produced today.
