TP,
Too bad your 93 was not an NV4500. GCWR is 2000 lbs lower than a 4l80e equiped truck. the 4l80e Pulls 10 mph slower up a 5-6^ grade, only can go up a 15% grade at 15K, an NV is 30% at 20K. I could pull those 5-6% grades with AC on, most I knew with the 4l80 needed AC off, and the water temp was still some 20F higher than my 96. Not sure what is so special about that 4 spd auto that took some 20 more HP to use vs the NV.
The only white knuckle times I had at 15-16K were not caused by weight issues. ie 30 15-20 passenger vans on a site seeing tour coming the opposite direction as me on a 1.5 lane mtn pass in Utah above Redfords ski area. that was fun. A buffalo walking down the middle of the road in yellowstone......realizing his horn would go thru the door and halfway into me!.......
I'll still take a slightly under power rig, that can handle the trailer vs an overpowered rig that is too small in payload!
