Patriot, run those numbers, I bet you're wrong. I rather pay fuel than down time, maintenance, etc. Plus they hold value very well. I change the oil in our toyotas, takes about 20 minutes while drinking a beer.
I'm an engineer, so I have a spreadsheet for everything. The amount you spend on gas is monumental compared to maintenance, down time, etc. on modern vehicles. Tundra owners choose to pay it in return for the benefits they enjoy in owning a Tundra, which is fine. But it doesn't mean the numbers don't still add up against it.
They do hold value well, but again, in 2019, if you get a good deal on a pickup, they all hold value pretty well. This isn't 2005 when Ram couldn't make a dash that didn't crack, Ford couldn't make a transmission that held up past 100k miles, and Chevy couldn't make a half ton with any type of reasonable towing capability. This is 2019, and Toyota infotainment systems are crazy outdated, their interiors look like Ram from 2012 (and Chevy/Ford from 2015), their engine power numbers are just ok, their efficiency is the lowest in class, and their prices are the highest. They need some major updates and they'll be right back on track.
FWIW, my dad got his 2019 Ram 1500 from Oklahoma City and got 25 mpg driving from there to Lindale. Towed his 6,500 lb trailer to Broken Bow today with no issues. Toyota is very capable of similar performance - they just need to spend some R&D and get it done.
Just for some quick numbers though - let's look at the first 100k miles:
Ram Ecodiesel (what I own) at 28 mpg on $2.50/gallon fuel - total fuel cost = $8,928
Toyota Tundra at 17 mpg on $2.10/gallon fuel - total fuel cost = $12,352
Total savings = $3,425
If fuel prices go back to 2009 values at $4 for regular and $4.50 for diesel, the total savings increases to $7,458.
Not trying to be rude, but I've definitely run the numbers a hundred different ways on this, and the cost of Tundra ownership far exceeds the rest unless you factor in major repairs for other brands but not for the Tundra.
