There is NO pay-back on truck mods --- the wheels, tires, exhaust, lift,and etc-- all cost, and never "Pay-Back" anything. The best pay-back is -- leave it stock and drive it.
People buy and mod their trucks, because they have $$ to spend, it makes them feel good---------- and it helps the economy!
I love my 5-6 conversion, and it does reduce the cabin noise at cruise.
Disclaimer added-- The addition of the 6 speed, probably will not give much of an increase in fuel mileage.
