Thinking of buying a 5.7 Dodge Magnum

Sorry if this is the wrong thread for this. I wanted to know if there are any critical problems with these boats before I make an effort to get one. I see a ton that are 130k+ miles but my Dad's 03 Ram is almost at 200k and is only just now the transmission(3/4 ton Cummins towing weekly) is starting to have weak shifts.

I've heard the 5.7 develops problems in its old age.

I'm asking you guys because i trust FABO much better then a salesman.

I hope I don't burst any bubbles but I am a Salesman. Not Mopars but industrial pumping equipment and I do have something to say about the 5.7 Hemi. I own a 2005 Dodge Ram Power Wagon 5.7 Hemi with 282 thousand miles on it still runs great. My second vehicle is a 2014 Ram Sport 5.7 Hemi getting ready to hit 200,000 miles and run strong I'm a Believer in the 5.7 you got to do the maintenance and don't be stupid with it and I'm looking to get 300,000 plus out of my Power Wagon. That's just my story
