I have heard and read that doing this work for economy is a waste of money. My experiences with other type vehicles have been most claims are greatly exaggerated.

What is the real scoop on this? As you guys know, it ain't cheap!

thanks
What are the details on your truck? Year? 2500/3500? Dually? All of those will play a factor along with driving style of course.

I personally saw 4mpg increase unloaded and 2mpg increase when hooked to the camper when I deleted my '12. That was with all else on the truck being stock.

Funny thing... When I upgraded to aftermarket wheels and 35s I lost 2mpgs when unloaded but towing mpgs stayed the same. Also, going from a 7000lb 27' camper to a 10,000lb 35' camper and towing mpgs stayed the same too. I say this proves that wind resistance is the bigger impact than the weight.

Regardless of the mpg gain, how the truck drives tuned over stock is the real reward and makes it worth every penny.
