Full time 4wd conversion kits?

[redrider036]

Hey gang, thank you for taking some time to read and help me out with this. I may be purchasing a 1976 scottsdale 4wd short bed. The truck is solid and I will be making a trip to Minnesota from Arizona sometime this summer, probably June. Does anybody have any experience with the Mile Marker or Warn kits that make the front hubs lockouts? I know that converting the transfer case would be a better alternative, but my budget may not permit that at this point. The lockouts seem like a cheap enough alternative that I was considering it. Any input would be greatly appreciated!
