thanks guys. Took the truck for it's first trip on the highway today and it ran like a clock. Round trip 138 miles and the fuel guage has hardly moved.
When we weighed the truck total weight was 6680Lb. The original weight over the front axle on the donor '83 dually was 3968Lb and it's weight now is only 3086Lb. I may need to replace the front coil springs with some slightly softer ones as it does seem to ride a bit hard in the front.
Other than that to say I am happy with the final result would be an understatement.
