I gotta ask... this isn't your first rodeo obviously, but I think it's safe to assume that it's more of a pain in the ass to do these builds on the new truck than it was 10-15 years ago.
How many factory features will you lose? I'm talking about creature comforts and electrical bugs. Is it normal to have an ABS light and a check engine light on these trucks because some random sensors get deleted?
I mean you are literally rebuilding everything from scratch! Incredible work man, I'm excited to see it finished.
