Propane injection works well when the cost of propane is low, relatively. The btu content per "gallon" (rough equivalent) is lower than diesel; maybe 2/3'rds. In some states (Utah) this is $$-efficient. In most others one simply has a dual-fuel vehicle to extend the range of available diesel (were there a shortage). The cost is easier to absorb than a CNG (compressed natural gas) conversion/addition, but CNG stations are fairly rare (search for nationwide locator); one can also spend $$$ for a home compressor station. Propane is widely available nationwide (and be aware that one must pay road tax for fuel in either case; an expensive citation if not properly registered).

Both add complexity and weight to the truck, not to mention reduced space.

Both should also be viewed on a graph comparing also WVO and WMO.

The great thing about a diesel is that all can be considered.
