This looks like the other forum discussion thread.
Looks like records should be established (if not already done). Fuel log here at EM.
5,260-lbs configured (same weight as my 1/2T 2WD 2001 high option Ram V8-318) against what specific drivetrain (drive, engine, trans, rear gears, tire height, etc)?
The commute can be figured with the trucks elapsed time counter (if so equipped) for travel time versus miles. Miles from the shop to the jobsite and back should be deductible.
Tire pressure set according to load?
Truck has hard tonneau cover.
As above, some instrumentation needed. The CAI may hurt more than help, so hold off on other mods until records baseline established for time, distance, fuel and use.
