man i think the 6.0 is either the biggest piece or the biggest beast... so far...(knock on wood) ive only had to do the hpop and egr delete. probably trade in end of the year or mid next year. but i love my 6.0... uncle of mine traded his 6.0 for a new chevy...traded a year later for the new ford... interior was his issue. i never found dodges to be to comfy inside. personal pref though.
