Some things don't take as many zeros, like an L8T or an L5P - although adding the DEF stuff shouldn't be too hard, the upshot is that there's likely several reasons why GM did not bother making the L5P available to the genpop in a Suburban.
My opinion is that GM is wrong about that ...
I think most of the reason (this is not substantiated by anything other than OPINION) why all Big 3 do not put their big diesels into their 1/2 ton SUVs is because ppl will do stupid things with them.
It takes 1 idiot saying “this is the same engine in a 3500 and I put a bigger turbo and injectors on this thing so I can tow 20,000,000,000,000 lbs”…….. and lawsuit.
That’s why we get the smaller diesels in 1/2 models.
