I am looking at buying an xterra and was curious about whether or not these things are true 4wd vehicles. I had a 1985 Blazer 4x4 and when in 4wd the tire that was loose would spin. Another words say one tire was on ice and the other was on pavement, the tire on the ice would spin and the tire on pavement wouldn't do jack. The dumbest thing I have ever seen. However, my brother had a 1984 F150 4x4 and it would spin all 4 tires regardless of terrian with any equal amount of tire rpm. I would like to know if the xterra will perform like the F150 or like the Blazer when put in 4wd.

Thank you,
