Myself and two friends bought 2 1985 Hilux's and 1 Four Runner with the 22R engine. They all ate 1 qt of oil every 3K oil change. Toyota said "within specs". Two of us dropped it and just carried oil everywhere on a new truck. The other friend with The Four Runner walked in front of the Toyota...
Time will tell if Toyota's much more complex system of small block engines pushed by two turbos will last. The new Tundra's are butt ugly with no tow hooks on most 4wd's, and the Tacoma is a bit better. Hopefully they raised the roof on the Tacoma's so I wouldn't have to sit an inch from the floor.
I have Carli's "soft" springs on my 2007 2500. I don't consider them soft with their Commuter shocks at all.
I'd go with Don's. Tough to beat a used Smarty tuner. They're in Marketplace all the time.
I was in Baja surfing and a guy with one invited me in to have a beer and get out of the elements. Sold. I got rid of my Toyota Hilux and bought a 1998.5 Ram 2500 and a Northstar TC800 popup. I never slept in a tent again.
