In my experience they are about as reliable as can be. I have seen some with over 300k miles on the road. Fuel economy is not great but what can you expect from a 3/4 ton 4x4. The exhaust manifold issues are the same for all the 4.8, 5.3, 6.0 engines. If they are in an environment that causes rust then the bolts will break off and you will need to extract them. Its actually super easy with a welder.
