Best half ton truck to own out of warranty

My Triton tick has been with me since about 30K miles. Most of it goes away after about 20 seconds of idling after start up, but I can hear it most of the time if it's quiet in the cabin. I've heard it's a non-issue the majority of time, but I often wonder if/when my turn is coming. It's not down on power, doesn't use one drop of oil between changes, doesn't leak, doesn't smoke and I now have almost 102K on it. Going in for spark plugs and coolant this spring. Might change the transfer case and dif lube while I'm at it, too. I need to get another 100K out of it before trade. I take care of it, but I don't baby it. Still runs like new. It's a great truck and there isn't much I'd change.
