worry wart

Hello to all
Complete newbie here with a question for all. I have had my dream truck for a month now with zero problems and I absolutely love it. It is a 2011 new to me crewmax with 122,000 miles on it and runs like a well tuned machine. My question is I have been reading about the 5.7 having timing chain tensioner problems on the driver side of the engine, so far mine is quiet as a mouse so should I keep worrying my self to deth about it or just ride and enjoy it. The car fax showed a good service history on it and I can tell the truck has been taken care of at a local dealer since new. Is there any thing I can do to prevent this problem or is it just something to look not forward to? As I said earlier this is my dream truck and I have worked a long time to get it and dont want anything to happen to it , a lot more payments to go

 

No problems with timing chain or anything else at 198K miles. No problems. No worries (not with my Tundra, at least).

 

Have it checked according to the dealer's/mfg maintenance guide...drive it and enjoy.

 

128K second owner every oil change on time , 81k even since owned, Chain tensioner I wouldn't worry about since with any thing you can hit the lottery meaning it can be great for a long time or it's unlucky and bad and or pro oil changes. if it is not making making noise or a current issue don't replace at low miles. If it was higher 200-300k mileage and having work performed in the area and would save move money to have replaced now vs later then do other wise don't worry.
