DEF level sensor issues?

Ehh you expect only 150k? Lol 300k at a minimum with superb maintenance I see being reasonable.

It better get to 150k no problem. LOL Meant to say i want to put 150k miles on it, plan is to run this truck up past 200k miles and then look into replacing it with whatever. At this rate it should take me about 8 years to do that. Maybe i'll be able to afford a '17 lariat by then....
