No worries at all, Steve. I'm glad you asked for the full Monty because it's important to share the correct information with those who have questions.
I haven't spoken to Outfitter about their new design so I don't know if they would fit older Toyotas.
I agree with you, Toyota trucks seem to be built heavier that similar duty trucks. And they seem to go forever. The rumor is the new 2018 Tundra will be available with a Cummins diesel. So the American Tundra will be on par with all the other foreign Toyotas out there that already have diesel engines.
