1st Gen Tundra or 2nd Gen Tundra

I'm looking into buying a Toyota tundra under 10 - 15k. I so far have 2 that I like, although both have decently high mileage. One of them is a 2005 SR5 with the 4.7l V8, with 191,000 miles on it. The second truck which I prefer a little more is a 2007 Tundra SR5 TRD Off-Road Pro 4.7l V8 with 240,000 miles on it, and a serviced timing belt 6,000 miles ago. The shocks on the rear were replaced, and it comes with two new struts. I am looking for a daily driver which can also be an off-roader when I want it too (both have 4wd). I am a little skeptical about the 240,000 miles even though I know there are numerous reports of these trucks going over a million miles. I am just looking for a better deal, that will last me a long time.
