Sounds very possible. The trucks made 300 hp at the crank. 13% lose for drag and what not equals about 210 at the wheels. 25 hp lose over 5 years is totally possible. 5 hp a year. It sucks but its the truth. Top Gear has done tests with cars that have lost over 100 hp throughout its life.

Uhh I don't really agree with that statement. Horsepower loss over an engine's life is possible, but the pistons, cylinders, rings, and everything else doesn't start truly wearing down until at least after 100k if driven normally. Do you have any CELs, and have you don't any maintenance on the truck? This truck still has a lot of life to it, there is no reason it should be putting out those numbers even considering drivetrain parasitic loss.
