2014 EcoDiesel engine longevity

Hi Guys Im new to the forum and in the process of purchasing a 2014 Ram EcoDiesel and wanted to know what kinda miles are expected from the 3.0 engine? The pickup im purchasing has 130000 miles on it already from a 1 owner.. I know thats a lot of miles for the year but the price it right and it looks like its been very well maintained. The carfax shows all the maintenance and services were done and no major issues. So my thought is if the pickup has made it through the 40000-80000 miles where there was a major worries of cam gear failure then it should be one of the good ones.. Well thats my hope haha.. Any feedback would be great..
