This is all true I suspect, but He was referring to a 2011, not a 2012 IBC, there not the same, the 12 works very well, the 2010-11 do not the Max Brake is better, but lots of things in life are always better.
No it wouldn't.
It looks pretty silly for you to continue defending the Ram oem brake controller even though you've finally admitted to yourself that the one in your truck does a lousy job.
The only owners who claim to like their oem brake controller are those who have never experienced the huge improvement in performance and safety of a brake line pressure sensing controller like MaxBrake, BrakeSmart, or the old Kelsey-Hayes manual brake controllers we used prior to the '90s.
