The Tundras and Titans do fine functionally as trucks. Toyota and Nissan just do not pour the amount of $$$ into them that Ford, GM, and Ram do to theirs to stay competitive in most aspects. The Nissans and Toyotas are kinda competitive about every 4-5 years, for 1 model year, after they do a refresh.
The Titans are cool in their own right, but just lack the interior quality of the Ford, Ram, and others. Its a shame they weren't able to take full advantage of that 5.0 Cummins V8 diesel, that sounded like a really neat engine. (Now discontinued.)
The Tundras look nice, but they still try to beat the "reliability" drum. Yes, if you use 5-10 year old technology, of course it will be more reliable than the under-5 year old stuff. I have a habit of getting into rants about how bad Toyota is, so I will just say one more thing... One thing that Toyota is doing, that is fantastic, is even their new base models are starting to come with a ton of safety technology. My brother-in-law just bought a base model Tacoma with very few options (tight budget), and he has automatic cruise and emergency braking. To get those on Rams/Fords/etc., you'd have to have at least a middle trim or higher, and pick/pay for the option as well. Even my Limited doesn't come with braking/auto cruise out of the gates, it has to be added as an option.
