My trucks front axel gains 400 pounds with my very large TC on board.
I have averaged 15.1 mpg diesel over the 10 years that I've owned it. I've neve been parked on the side of the steep mountain roads with the hood up... like the vehicles you've seen...where they are waiting for a tow truck. (BTW... the Tow Truck will most likely be a diesel)
Hoods up along highways in the desert... no way, didn't have to turn off my air conditioner either.
I didn't have to "chip it" to get up the mountain.
I didn't have to add a oversized tail pipe extension to fool people into thinking that Ihad a diesel.
No special noise making mufflers... just to pretend that I had a real truck (diesel)
The cost of fuel has to be calculated with the large increas in fuel economy for the diesel... 30% or more.
No spark plugs to blow out or foul...
My trucks Duramax is paired with the Allison transmission... you won't see many of these in the shop...
So... the diesel engine with a very strong transmission costs 5% to 8% more when new... and is worth more at resale... with a 30% to 40% fuel savings over it's life or 300000 miles... and a much more dependable ride.
It boils down to... DO YOU HAVE THE MONEY?
If you can't afford it will you be the one to find any excuse to buy the cheaper option?
Often, the guy that screams the most about weight limits brags about how he always breaking the speed limits... how he has too or get run over! :B
If you can read the door post... then for goodness sake read the speed limit sign.
My system works for me... and when you take everything into consideration... it might work for you!
