Hi. Not the same change, but I went from a 40DP with a Cummins 400ISL to the 7.3, ten speed and 4.30. Tow a 13.6K fifth wheel with about 21K on a 26K GCWR.
TFL Truck towed 16K up the IKE with this combination, so it can go anywhere you need to. You will have substantial downshifts on the hills, but the same transmission is rated for 43K in the F-350 diesel, so I think it will be fine.
I do not track mileage carefully, but guess I am at 14 empty and 7 towing.
The gasser is much better for me -- about 75% of miles are not towing. I am getting used to the long bed, but the SRW is much better for parking in town.
