What is the cost of inadequate power?
My 8.1 Chevy Big Block has more than enough power.
I have told people many times, get the vehicle that beat suits your needs. If you tow a flat bed daily, and rack up the miles with heavy loads, by all means get a diesel. My situation called for a gas. I drive 1.5 miles to work daily. Tow a TT about a dozen times a year......so I went with a truck that has about as close to diesel power as you can get.
