First off nice truck. I am one that does like the new look.I am looking a 6.2L because it will be sitting sometimes
between camping trips. The 6.7L does not like to sit long periods of times.
Where did you see taht the 6.7 does not like to sit. I leave mine sit for weeks at a time during the winter. I have actually only put on 500 miles in 3.5 months. Truck is for pulling a trailer. Everything I have heard is no problem leaving them sit just keep the fuel tank full.
