Hey folks. I have a 7.3 that has just become too much work to keep as a daily. I have an opportunity for a 2013 w/45k miles and a plow or 2016 w/60k. Same price. Might be a no Brainer, just wondering if the 3 years and 15k mile difference should matter. The 13 is in immaculate condition, going to look at the 16 in the am... anything I should look for? What are your thoughts on which one? Thanks.
