From what I've been reading, these braided hoses "typically" have a PTFE inner hose. I don't know how rare it is for the inner hose to be rubber, or if such a composition actually exists for brake applications, but if so, then it would be reasonable to expect similar longevity as a regular OE rubber hose.
In my experience, OE rubber tends to last for about 20 years. But when I try to google an average life expectancy, I'm getting a lot of estimates saying 6, 8, 10 years. And I can think of a few different explanations as to why such low numbers are leading the search results...
Of course the nice thing about rubber is that while you can't see the inside of the hose, you can still get a general sense of its condition by inspecting the outside. So you can decide for yourself whether your decade-old hoses really need to be replaced yet or not. (Just saying that in general. I know OP's truck is more than 10 years old lol.)
And while I'm not seeing it anywhere on the maintenance schedule for our trucks, I'm still a firm believer in brake fluid changes every few years. Especially on ABS systems where particles can screw with the valves. But even on non-ABS systems, I've noticed a significant improvement in brake feel when old fluid gets changed on a neglected system. And there's something to be said for having the excuse to crack the bleeders every few years to keep them from getting seized (especially up here in the rust belt...)
