Glen,
Exact reasons I bought the 4600LP, even tho it had the same engine as the For SD or pre 450 15K gvwr, or the GM 3500HD ie a pre 4500 15K gvwr. The REST of the 4600 was much more truck. I did not need nor require the HP of a DT466 or 360. Altho I admit at times I wish I had the 235/620 T444E, but that would have been another $6-7K, $10K for a DT like you have which would be the cats meow for how I use my truck. Mostly local doing under 55 mph, a few forays on the interstate at 60, now where legal per say to drive over 60 for 100 miles N, S, E or West for that matter.....
At the end of the day, it is choosing the truck that fits ones needs and desires from a carrying standpoint, power/speed standpoint, and gearing such that one can go up a certain % grade with out stalling out! be it lack of gearing but power there, did that with many 454/TH400 1 tons, or lack of traction.
