I also have a deuce with an LDS which came from GL in Mechanicsburg, PA. My brother drove it back to Keyser, WV and I drove another one with an LDT. There are a few steep grades between there and here and, while I had to downshift (sometimes to third) my brother never did. A lot of difference. If you have any problems/questions, I (or other members I'm sure) could get you pictures, etc. I've never had any cooling problems and when my brother drove it back in 80-85 degeree weather for about 5-6 hours on the linterstate, temperature never went above 180 even on the grades.
