GMW...a VERY good point and now that you have me noodling that aspect...
It should or has to also be able to turn on the trailer brakes, other
wise while braking the TV in a severe condition...a potential jack knife
situation if the trailer brakes are NOT involved
The IBC's on some use the TV's ABS and traction control where they
can either or both set the TV's brakes at an individual wheel and
or reduce braking in one wheel
I would also assume that it can NOT provide additional throttle
So this situation would have the TV's IBC giving braking to any one
or more wheels, reducing braking in any one or more wheels, maybe
provide throttle (?...don't think it is at that level of computer
control yet...though throttle by wire has this ability there),
assume ABS buzzing on some that are skidding ***AND*** initiating
the trailer brakes to some level to 100% voltage
BUT...without the WD Hitch, can the TV manage the whole setup? What
about the TV's weight distribution? Will it be too light on the front
axle without the WD Hitch setup?
What does the IBC 'think' the TV's weight distribution is? Does it know
that the WD Hitch system is NOT there?....or does it assume that the
front axle is back to whatever weighting the manual instructs to setup?
