Should I be worried about the engine, I know Ford made some improvement since 2011 so ...? (btw, anyone as a link to the evolution of the ecoboost: history of improvement ?) As always, Thanks for your feedback
If it's a 157" WB (screw w/ 6.5' bed) be aware of a shudder from take off due to axle wrap.
There were multiple attempts at fixing a known condensation issue with the EB. I would have ford run a report and see what TSB's were applied. CAC may have been replaced or blocked, multiple updates to the PCM, etc.
I disagree with improvements to the EB post 2011. If you can find an unmolested 2011 with the original CAC I'd be happy. I only had one of the first revisions done to my PCM and have the original CAC, never had a condensation issue.
The new CAC is inefficient and the updated PCM strategies supposedly nerf the engine a bit as some report.
