The leaf spring 70 series are rugged military pattern light trucks widely used in mining and other industrial operations around the world. They are trucks not SUVs. The coil spring 70 series are SUVs designed to look like military pattern light trucks.
If your daily commute is at least 10 miles for a diesel, traveling not much more than 65 MPH, mostly on 2 lane open roads, then a RHD 70 series will be very reliable in almost any kind of weather. However if your daily drive is high speed city traffic you will be at a serious disadvantage and the RHD will give blind spots that make congested traffic challenging. It's rugged and reliable, but not at all nimble in traffic, unless it's a turbo version, but even then it's marginal. On the plus side, it will survive almost any accident, when any other vehicle would likely be totaled.
I consider mine the best truck I've ever owned, with the highest quality and the lowest maintenance cost of any others I've owned including Broncos, Blazers, Jimmys, Suburbans and IHC Scouts. I wouldn't trade it for anything else I could buy today. They are made to be maintained and run for hundreds of thousands of miles and passed on to the grandkids.
