Forgot:
If yours does NOT have the factory tow option, then install the engine oil cooler
(it runs to the hot tank of the main radiator), an external ATF cooler and do NOT
tow heavy in OD
Get the largest AFT cooler you can stuff in there and plate types best for this
application.
This is a picture of my Suburban while in the shop fixing the damage hitting a
SUV which jumped a stop sign...
It is on the drivers side of the center support/horn...right side
on this image and between that and the headlamp is the power steering
fluid cooler (tube/fin type)
