Thanks for the replies.
I’m looking to stay away from the newer diesels for simplicity and the complexity of the newer emissions.
I like the fact the Chevy 6.0 has been around a long time and seems to be very reliable.
I’ve always heard about the better leg room but since I always drove never really thought about it. However, riding passenger in my Brothers class C I quickly realized the issue. Could not get comfortable on the passenger side.
I also just read a post on the Towing forum about some valve train issues and engine replacements with the new 7.3.
