The difference is very noticeable. At no time do I need full throttle on the truck while towing, althought there is significantly more drone from the exhaust. I won't be able to check EGT's until I hit some longer grades. The disk brakes are excellent --- application of the brakes is much quicker and very smooth. Moving to radial tires has significantly softened the trailer ride and noticable in the truck on rough roads. I normally get 8mpg towing this rig, looking forward to a longer trip to see if the combo yields higher mpg's.
