How old a factory radiator hose would you run? How 'bout heater hoses?

When did today's "advanced super-rubber" radiator hoses debut?

I'll be examining mine tomorrow.

 

In the south where temps are warmer and dry or extremely cold climates I would say 15 years is about if for rubber anything, moderate temps and humidity 20 years

There is no "advanced super-rubber", its called metal and it ain't real flexible, lol
Rubber or similar compounds dry out and crack, under the hood they last longer than in direct sunlight

 

I've had my main hoses on since the truck was new in 01. I replaced all the others when I refreshed the engine due to location and accessibility while it was out of the truck.

 

Listings of hose manufacturers include: AC-Delco, Continental, Dayco, Gates and Motorcraft.
All ring "good" to my ear. Are their any baddies in those 5 companies? I'm leaning toward Gates.

Also, the several heater hoses and heater hose assemblies are a tad confusing. Is there a simplified list of what a particular truck has?
