Hi, some of you guy's seem to really know you're K-Trucks. I'm hoping you might be able to help me out with my research, any info would be greatly appreciated. I'm planning on buying a 73-87 K10 LB 350/auto/NP 203 T-case I want the full-time 4x4 because of the superior and safer road handling that comes with this system. I currently own a 98 Jeep Grand Cherokee with Select-Trac which gives me the option of full-time, part-time, or 2wd. I leave it in full-time 4x4 since it is very clearly more stable when cornering at speed, and there is little or no difference in fuel economy, just as the manufacturer claims. However, I'm hearing that the NP 203 is a real gas guzzler. How bad is it? Are there any other problems with this T-case? does it give the same handling advantages that I get from my Jeep? Or, are there any other full-time systems available to fit the K-Trucks? Thanks.
